Much Acid There is in a Solution During the extraction of a metal from its ore, sulphur dioxide is often produced. It is converted into Sulphuric (VI) acid and sold as a useful by-product. I shall be carrying out a titration between sodium carbonate, a weak alkali, and sulphuric acid, a strong acid, to calculate the concentration of the sulphuric acid. The sodium carbonate sample I shall be using is a solid. Solids cannot be titrated successfully, so I will turn it into a solution by adding
Sulphuric Acid in a Solution Through a Titration Aim: To find the exact concentration of sulphuric acid in a solution through a titration. The titration is between sulphuric acid and sodium carbonate has to be in liquid for in order to carry out the experiment so it is dissolved into distilled water to a concentration of 0.1 mol dm³ Introduction- ------------- During the extraction of a metal from its ore, sulphuric dioxide is often produced. This is converted to sulphuric acid and is
The Effect of Sodium Thiosulphate Solution on the Rate of its Reaction with Hydrochloric Acid Aim I shall investigate how the concentration of Sodium thiosulphate solution affects the rate of its reaction with hydrochloric acid. I shall add water to the sodium thiosulphate solution to weaken the concentration so I can see how concentration can affect the rate of reaction. I shall add water as that is the only way I can find out how concentration affects the rate of reaction as I cannot
the Addition of Sulphuric Acid and Sodium Hydroxide Solution Aim To investigate the temperature changes during the addition of sulphuric acid and sodium hydroxide solution. Introduction In this experiment we are using sodium hydroxide, sodium hydroxide, sulphuric acid. We are trying to find out how much acid it takes to neutralise alkaline. But there are many things that could effect my final result and I think that the main thing will be measuring the acid and alkali out accurately

[IMAGE]Sodium + Hydrochloric Sodium + Water + Sulphur + Sulphur Thiosulphate Acid Chloride Dioxide (aq) (aq) (aq) (l) (g) (s) The reaction makes the solution go a yellow cloudy

The equipment need is as below: · Solid calcium hydroxide · Methyl orange indicator · Volumetric flask (250cm3) · Clamp and boss · Clamp stand · Burette (50cm3) · Conical flask · Pipette (25cm3) · Pipette filler · Distilled water · White spotting tile · Hydrochloric acid of chosen concentration · Beaker
training about safety and health. Shop hazards can be avoided by following the safety rules and procedures of the shop. Here are some hazards. * Flammable liquids must be stored properly away from fire. * Batteries contain corrosive sulfuric acid solution and produce explosive hydrogen gas while charging. * All types of liquids can be harmful either to the skin or eyes. *High-pressure air can be very dangerous if penetrates the skin and goes into bloodstream * Electrical equipment and lights may
Chips and Hydrochloric Acid The aim of this experiment is to find out how different variables affect the rate at which the reaction between Marble chips (CaCO ) and Hydrochloric acid (HCl) takes place. There are many variables that affect the rate of this reaction such as the following: 1. Temperature 2. Concentration (Pressure for gases) 3. Catalyst 4. Surface area In my investigation I will be testing how changing the concentration of the Hydrochloric acid. The aim is to find out
because I believe it will create better results and make an easier experiment. Prediction: I believe that when the temperature is increased the particles energy will increase there for creating more collisions between the magnesium and the acid. In effect increasing the speed of the reaction. Preliminary work: After doing various experiments in my preliminary work I decided to use: -20ml of 2HCl -20ml of H2O -5cm of magnesium ribbon -Starting temperature of 20o -+10o
The Molecular Formula of Succinic Acid The relative formula mass is the mass of 1 molecule of succinic acid compared with 1/12th of the mass of an atom of carbon-12. This is obtained by adding together the relative atomic masses of the atoms within the molecule according to its written formula. However we do not know the exact formula: HOOC(CH )nCOOH Where n is a whole number between 1 and 4 So to calculate the relative formula mass I must use the formula m = n ×Mr
Discussion Unknown Solution 1 I believe that the first unknown solution is made up of molecular compounds. This is because the solution had very little conductivity, meaning there was not an equal amount of ions broken down in the solution. The solution had no scattering, which means the molecular compounds were fully dissolved in their solvent, which was not water. When tap water was added to solution 1, the color changed from green to blue. If water was the original solvent, we would not see this
of the Ca(OH)2 is between 1 to 1.5g per dm3. Also I am given a standard solution of 1M hydrochloric acid (HCl) which may have to be diluted to suit the measuring needs of the experiment. Apparatus: [IMAGE] * 1g of Ca(OH)2. * Pipette 25cm3 * 2 x 500cm3 beaker * Conical flask 250cm3 * Burette * White tile * Burette stand * Stand * Indicator * 300cm3 of Hydrochloric acid- standard solution (concentration of 0.05M) * Distilled water * Filter Paper * Stirring
Investigating Which Metal Combination Gives Out the Most Voltage in a Solution Background Metals are an order of chemical elements in the periodic table. They are arranged in atomic number. All of them are solid (apart from mercury), good thermal and electrical conductors and are shiny when polished. Metals and non - metals are separated in the table by a diagonal line. -------------------------------------------------------------------- The reactivity series is a table to show
gaseous solvent to form a solution [1]. The solubility of a particular substance is dependent on the physical and chemical properties of both the solute and solvent [1]. The temperature, pressure and pH of the solution also has an effect on the solubility. The extent of the solubility of a certain solute in a particular solvent is measured as saturation, where adding more solute will not increase the concentration of the solution and will precipitate the excess in the solution. Phase transfer reagents
is highly beneficial to be able to calculate the concentration of a saturated solution. Indeed, knowledge of the concentration is required to calculate solute solubility and if precipitates will form when the solution is mixed with other reagents. This has many applications in industrial processes. For these reasons, this experiments aims to determine the concentration of a saturated barium hydroxide (Ba(OH)2) solution by conductometric titration and gravimetric analysis. Conductometric titration
and creating a calibration curve. Finally, the last goal to finish the project was to determine the amount of phosphoric acid in the cola beverages. The phosphoric acid content
throughout this experiment · Wear safety glasses to protect eyes · Handling the acids carefully · Careful while using kitchen knife (And all the simple things such as not running etc.) Another important aspect before we start is making the experiment a fair test. This includes making sure the volume of each acid is the same using a measuring cylinder. The same temperature for each individual solution will be the same as they will be done one after the other and left for the same amount
lower than the concentration in the cytosol, the solution is said to be hypotonic to the cytosol, in this process, water diffuses into the cell until equilibrium is established. If the molecules outside the cell are higher than the concentration in the cytosol, the solution is said to be hypertonic to the cytosol, in this process, water diffuses out of the cell until equilibrium exists. If the molecules outside and inside the cell are equal, the solution is said to be isotonic to the cytosol, in this
Preparation of Ethanol and Ethanoic Acid Introduction to report ---------------------- This report contains 5 practical experiments to produce ethanoic acid from ethanol. The first practical is the preparation of ethanol from glucose using yeast during the process of fermentation; this has been demonstrated in class. In this practical the glucose is converted into ethanol and carbon dioxide by respiratory enzymes from the yeast. The ethanol solution will be between 5-15% and the ethanol
the electrolysis of acidified water affects the rate at which hydrogen gas is produced. The solution to be electrolysed is made up using acid and water. It is of little consequence what acid is used however in this case I will use Sulphuric acid (H2SO4). When H2SO4 is put in water it is dissociated and forms ions: H2SO4 → 2H (2+) + SO4 (2-) Ions are also present from the water in the solution: H2O → H (+) + OH (-) During the electrolysis process, the positive hydrogen ions move
