NaCl Effects on Peroxidase Activity My experiment was to see if adding NaCl to solution would have any effects on peroxidase activity. The materials that were used in this experiment were pH 7 buffer(DI water)‚ peroxidase‚ NaCl‚ guaiacol and hydrogen peroxide; added in that order. Blanks were created for each NaCl concentration‚ 0%‚ 5%‚ 7.5% and 10%. Each cuvette had .5ml of pH 7 buffer‚ 1ml of peroxidase‚ .02ml guaiacol for the experimental cuvettes and 0ml of guaiacol for the blank cuvettes‚

The Effects that 1%‚ 4%‚ and 16% Sodium Chloride (NaCl) Concentration Had on the Rate of Reaction of Catecholase Enzymes in a Potato (Solanum tuberosum). Abstract Enzymes are a key component of a cell. They make chemical reactions happen faster because they lower the activation energy to make the chemical reaction occur. Most of the time‚ it is best if enzymes produce as efficiently as possible‚ but in some cases it is better if they do not‚ when dealing with potatoes (Solanum tuberosum).

NaHCO3 with HCl to form NaCl and two other products and then calculate the mole relationships between NaHCO3 and NaCl and calculate a balanced equation for this reaction. Safety: • Wear safety goggles at all time • Handle all chemicals with care • Use equipment like tongs when handling warm/hot objects • If chemicals are spilt on self‚ wash off immediately • Stand at all times Hypothesis: The NaHCO3 will react successfully with the HCl and will form NaCl‚ H2O and CO2. Then be able

Extracting NaCl from Rock Salt and assessing its purity Aim The aim of this experiment was to obtain a pure product from a solution through the processes o extraction‚ filtering and evaporation. Introduction Extraction is used when trying to separate or purify a product. For an extraction to be successful the substance used to make the solvent should readily dissolve. The substance used in this practical was rock salt. The liquid used should not react with the substance that needs extracting

atomic mass. When a compound is made‚ these relative atomic masses are added together to calculate the relative formula mass of the substance. For example the atomic mass of Na is 23 and the atomic mass of Cl is 35.5 so the relative formula mass of NaCl is 58.5 How by using RFM is it possible to work out amounts of a substance in terms of moles? The compound I was using in my experiment was NaOH. The first thing I needed to work out was the number of moles I needed. To do this I used the formula:

dissolved NaCl in water effect the volume of one drop? Aim: This experiment plans to measure the volume of one drop of water and compare it the volume of one drop of sodium chloride solution. What will be attempted by this experiment is to measure the volume of one drop of distilled water by measuring a control and comparing it the volume of one drop of distilled water with dissolved NaCl. This will be done by using a burette for dropping the distilled water and a electrolyte solution. Hypothesis:
