Determining the Concentration of Sulphuric Acid Risk assessment · CorrosiveAs sulphuric acid and sodium hydroxide are both corrosive, I will wear gloves, goggles and lab coat when performing the experiment · Eye protection must be wornIf any breakages occur I will carefully dispose of the glass in a suitable bin. · If any spillages occur during my experiments I will clean them promptly. Dilution of H2SO4 As the concentration of the sulphuric acid~10moldm-3, it is too concentrated
ackground Sulphuric acid is considered to be one of the strongest acids. It was first discovered in the 800A.D by an Islamic chemist by the name of Jābir ibn Hayyān. It is also the world’s most important industrial chemical, often called the “oil of vitrol”. It is a diprotic acid and is very corrosive and it able to eat through many organic substances and the acid is soluble in water at all concentrations. One of the reason as to why sulphuric Acid is important to the chemical industry because it
of 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
During 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

Chemical Equation Zn + H2SO4 H2 + ZnSO4 How my investigation is a fair test In this experiment only one factor is to be changed to make it a fair test, the concentration of the sulphuric acid, while all others must remain constant. I will also use the same amount of

Apparatus needed: - ------------------- Requirements to produce a Sodium Carbonate solution: - ====================================================== Electronic Balance (accurate to 2 decimal
planet is Venus, the second from the sun. This "sister planet" of Earth proved to have extremely hostile conditions. Scientists were hopeful when they found traces of water vapor in the upper atmosphere, but were disappointed when concentrations of sulphuric acid were discovered mixed with the water. Venus has surface temperatures of around 600 degrees Fahrenheit, and an atmosphere one hundred times as thick as the Earth's. (This produces pressure equivalent to pressure two miles under water on Earth.)
A conical flask was swilled out with water and a pipette and pipette filler were used to withdraw 25.0cm3 of the sodium carbonate solution from the volumetric flask and transfer it to the conical flask. A burette was first swilled with sulphuric (VI) acid using a clean, dry beaker and a funnel and then filled to below the zero mark. A little of the solution was then run out of the burette into the beaker and the funnel removed. A white tile was then placed underneath the conical flask and
Finding out How 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
Altering the Amount of Heat Produced When Magnesium Reacts with Sulphuric Acid When energy in the form of heat is given out of a reaction it is an exothermic reaction. Exothermic reactions usually need activation energy, the energy to break the bonds in the chemicals and to start the reaction. Once the bonds are broken new stronger bonds are formed. In an exothermic reaction energy in the form so heat is given out to the surrounding when the products are formed. Therefore there is an average
Acid Mine Drainage For hundreds, even thousands of years, human beings have mined for metals and stones, and with the advent of greater technology as well as greater needs, the demands for these resources continue to grow. While these resources benefit our lives in many ways, the effects of mining can be detrimental, and one such effect is the topic of this essay, acid mine drainage (A.M.D.). The causes of A.M.D. will be discussed, along with some of the physical and biological problems associated

of an alkali, on the volume of acid needed to neutralise it, when acid is added to it? The plan is to use two acids (Hydrochloric & Sulphuric) and one alkali (Sodium Hydroxide). The reason I need to use two acids is; because the question applies to all acids and alkalis and to just use one of each would not enable me to come to a general conclusion. If there had been more time available, ideally I would have preferred to use two alkalis as well as two acids. Predictions First of all
investigation, I will assess how changing the electric current in 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

is given out in neutralizing sodium hydroxide (NaOH) using different concentrations of Hydrochloric Acid. Background Information:- Substances that neutralize acids are called alkalis. An acid is a substance that forms hydrogen ions (H+ ) when placed in water. It can also be described as a proton donor as it provides H+ ions. An example of an acid is hydrochloric acid (HCl), Sulphuric acid (H2SO4) etc. An alkali is a soluble base and forms hydroxyl ions (OH-) when placed in water. It can
Decomposition of Marble Buildings by Acid Rain Background Acid Rain: Nitrogen acids and sulphur dioxides come out of tall chimneys and vehicles. These go into the air, and air currents carry the gases away, and they react with water vapour and oxygen. This produces H2SO4 (sulphuric acid) and HNO3 (nitric acid). The acids become part of a cloud, and it falls down to earth, as acid rain or snow. This can end up miles away from the original source. The acid rain removes nutrients from soil, so plants
Investigating the reaction Between Sodium Thiosulphate (Na2S2 O3) and Hydrochloric acid (HCl) Aim --- I am investigating the rate of reaction between Hydrochloric acid (HCl) and Sodium Thiosulphate (Na2S2O3), when Na2S2O3 is mixed with water (H20). Background Knowledge The rate of a reaction can be speeded up by increasing the temperature; at a higher temperature the particles move faster and collide more often, as a result of this the reaction speeds up. Increasing the concentration
