A sample of potassium hydroxide of mass 9.670g was dissolved in the water and diluted to the mark in a 250.0ml volumetric flask. It was found that 21.56ml of this solution was required to reach the stoichiometric point in the titration of 15.0ml of a sulphuric acid solution.
1. Determine the molarity of potassium hydroxide in step1.
2. Calculate the moles of [OH-] ions in step one.
3. Write down the balanced equation for the reaction in this titration in step 2.
4. Determine how many moles of potassium hydroxide in 21.56 ml solution?
5. Using the solution stoichiometry, determine the molarity of the sulphuric acid solution.
6. Explain what would be the estimated pH of the resulting solution at the stoichiometric point in step 2?
