2. Determining the enthalpy change of a reaction using calorimetry
This topic involves using calorimetry to determine the enthalpy change of a chemical reaction. Students can use different reactants and measure the heat of the reaction to calculate the enthalpy change.
3. Investigating the effect of concentration on the rate of reaction between magnesium and hydrochloric acid
This topic involves investigating how the concentration of hydrochloric acid affects the rate of the reaction between magnesium and hydrochloric acid. Students can measure the time it takes for the reaction to occur at different concentrations of acid.
4. Determining the molar mass of an unknown compound using freezing point depression
This topic involves using freezing point depression to determine the molar mass of an unknown compound. Students can measure the freezing point of a solution of the unknown compound and a known solvent and use the change in freezing point to calculate the molar mass.
5. Investigating the effect of temperature on the rate of reaction between hydrogen peroxide and catalase enzyme
This topic involves investigating how the temperature of the reaction mixture affects the rate of the reaction between hydrogen peroxide and catalase enzyme. Students can use different temperatures and measure the time it takes for the reaction to occur.
6. Determining the amount of vitamin C in fruit juice using titration
This topic involves using titration to determine the amount of vitamin C in a sample of fruit juice. Students can use a standard solution of iodine to titrate the fruit juice and calculate the concentration of vitamin C.
7. Investigating the kinetics of the reaction between iodine and propanone in acid solution
This topic involves investigating the kinetics of the reaction between iodine and propanone in acid solution. Students can measure the rate of the reaction at different concentrations of reactants and use this data to determine the rate law for the reaction.
8. Investigating the effect of concentration on the equilibrium constant for the reaction between iron (III) ions and thiocyanate ions
This topic involves investigating how the concentration of reactants affects the equilibrium constant for the reaction between iron (III) ions and thiocyanate ions. Students can measure the concentration of reactants and products at different equilibrium positions and use this data to calculate the equilibrium constant.
9. Determining the rate law for the reaction between hydrogen peroxide and iodide ions
This topic involves determining the rate law for the reaction between hydrogen peroxide and iodide ions. Students can measure the rate of the reaction at different concentrations of reactants and use this data to determine the rate law and rate constant for the reaction.
10. Investigating the effect of temperature on the solubility of salt in water
This topic involves investigating how the temperature of the solvent affects the solubility of a salt in water. Students can measure the solubility of a salt at different temperatures and use this data to determine the enthalpy of solution for the salt.
