Equipment: I will need a burette, 25ml pipette, pipette pump, white tile, clamp stand, boss head, clamp, 250ml limewater, phenolphthalein, 100ml hydrochloric acid, volumetric flask, distilled water, conical flasks, safety gear
Determining the Concentration Of Limewater Solution Aim: The aim of this experiment is it to find out the concentration of Limewater by performing a titration with hydrochloric acid which has concentration exactly 2.00M.. What is required for me is that I have to design my own experiment and chose the right and appropriate apparatus and equipment. I will be provided with 250cm3 of limewater, which has been made to which contains approximately 1g/dm3 of calcium Hydroxide. This hypothesis from
one substance to start with’. I came across this information in the EDEXCEL Modular Science revision guidebook 1. Thermal decomposition is the breakdown of a substance using thermal energy, this is not a reaction. Preliminary experiment Limewater and copper carbonate were used to see if a metal carbonate beaks down to produce carbon dioxide. This is what the experiment looked like: The equation for this: CaCo3(s) CuO(s) + Co2 (g) This experiment was to see if carbon dioxide
Determining the Concentration of a Limewater Solution Introduction Previous to conducting my experiment, research was carried out and the results of it adapted to aid me in solving the problem set. In the Advanced Chemistry Student’s Book by Nuffield, on page 86, I found a similar experiment to mine with a description of implementation, which aided me in the fact that I discovered the temperature of my solution did not need to be taken. This was because the solution of calcium hydroxide
straight into HCI the reaction makes the HCI become see through and clear but during the process the HCI i become a blue like Colour. The reaction when the copper carbonate is heated and vapour of the chemical is then directed into a chemical called limewater
spoiling the product, this is because the solution is quite delicate and becomes easily spoiled. Equipment/ Apparatus: * Yeast Culture * Apple Juice * Calcium Chloride Solution * Sodium Alginate Solution * Distilled Water * Limewater * Disinfectant * 2 Conical Flasks (250cm³) * 1 Bung and Delivery Tube * 2 Conical Flasks (100cm³) * 250cm³... ... middle of paper ... ...d this way they are capable of gathering oxygen. My results came out slightly incorrect
Add baking soda into Erlenmeyer flask until the reaction stops. Measure and record the temperature of the citric acid and baking soda solution, transferring no liquid. Fill half a test tube with limewater. Pour off the gas at the surface of the Erlenmeyer flask into the test tube half filled with limewater. Stopper and shake the test tube. Experiment B: Pour hydrogen peroxide until the test tube is 1/3 full. Measure the temperature of the solution. Add a small amount of manganese IV oxide to
reactions of a typical acid (dilute hydrochloric acid) with metals, metal oxides, carbonates and bases. APPARATUS The following materials in order to complete this experiment: Dropper bottles containing 0.1M solutions of hydrochloric acid or limewater (calcium hydroxide) and sodium hydroxide. Dropper bottle of bromothymol blue indicator Small samples of the following metals: zinc, copper turnings, magnesium and iron Copper (II) oxide powder Magnesium oxide Marble chips (calcium carbonate)
What is Empacho? Empacho, when related to gastrointestinal problems is, in a sense, a form of indigestion and one of the most common folk ailments in a Hispanic culture10. By some people it could also be more of a belief and described as a blockage of the stomach and intestines, as a ball of sticky undigested food, or foods that are hard to digest. This can result in symptoms such as pain, nausea, vomiting, bloating, etcetera. This being said, there are several different forms of empacho. One of
Titration Investigation Aim: The aim of my investigation is to determine the solubility of calcium Hydroxide solution with the aid of the titration process. Titration can be defined as the method of determining the concentration of a substance in solution by adding to it a standard reagent of known concentration in carefully measured amounts until a reaction of definite and known proportion is completed, as shown by a color change or by electrical measurement, and then calculating the
Limestone: What is limestone? Limestone is a sedimentary rock that is widely found in New Zealand. The rock is made up of more than 50% calcium carbonate (CaCO3) which is derived from the shells of tiny marine fossils. Limestone commonly forms in shallow marine water from a build-up of marine organism’s fossils. In the Waikato there are two major quarries where limestone is formed, one in Te Kuiti and another in Otorohanga which is near where the Waitomo Caves are based. In this report, I will be
Fragment of a Roman Fresco The Fragment of a Fresco is dated to 50-25 B.C., generally categorizing it into the Second Period of Roman paintings and placing its creation during the time of transition of Rome from a Republic to an Empire. This particular fresco was discovered in Pompeii, which is considered one of the leading sites of such pieces of art. While many Roman frescos throughout all four styles depict scenes of historical importance in both military and cultural aspects, this particular
Sedimentary Rocks Sedimentary rocks are formed from layers of deposits laid down in lakes or seas. Over millions of years the layers of sediment build up resulting in the weight pressing downwards, creating high pressure, which squeezes the water out. As the water is squeezed out, salts form between the particles of sediment due to crystallization and this cements the particles together. Sedimentary rocks can either rise to the surface again to be discovered, or they can descend into the
Glucose Concentration on Anaerobic Respiration in Yeast Aim:To investigate the effect of glucose concentration on anaerobic respiration in yeast. Equipment list: 2* conical flask Delivery tube with bung Dropper Yeast Glucose Limewater Water bath Stopwatch Measuring Cylinder Method:I am going to do 5 tests & each test will be performed 3 times to get an average result. In one conical flask, I will mix together 25ml of yeast & 25ml of a glucose solution, with a delivery
all pulp and thus increase the accuracy of the result vi. One possible improvement could have been to add an extra part to the investigation, involving the formation of a calcium citrate precipitate from the citric acid in the lemon juice (using limewater of a known molarity), which could be extracted and weighed: vii. This would allow the determination of the percentage of citric acid in the lemon juice specifically, rather than the total acidity. The results of this could have been compared to those
I believe my molecule could be a Ketone because of its very high boiling point and solubility. The boiling point is 145.5˚C. The molecule I have been given is very soluble in water. There are dispersion and Dipole-dipole forces between each Ketone molecule. Oxygen is more electronegative than carbon, so it tends to pull the electrons towards the oxygen. One of the two pairs of electrons from the carbon-oxygen bond is easily drawn towards the oxygen. This makes the bond highly polar. This is why the
Art is the application of creativity and imagination usually expressed through a visual form such as paintings and sculptures, that produce works admired for their beauty and delicacy. The word Renaissance means "rebirth". It took place between 1300-1600 A.D, following the Middle Ages (Britannica, 2018). The Renaissance was the reawakening of art, science, and culture. It was the golden age of arts. Leonardo da Vinci and Michelangelo were two extraordinary artists who contributed beautiful masterpieces

1. Definition of Acid and Bases: 1.1 Arrhenius definition of acid and base: Arrhenius Acid: The substance or a compound which gives H+ ions in aqueous solution Arrhenius base: Base is a substance or compound that produces OH- ions in aqueous solutions. Chemists have known for some time that the H+ ion doesn’t exist in aqueous solutions as an independent species. The modernized Arrhenius definition of acid is that they are substances that produce H3O+ ions in aqueous solutions. It did not take longer
