a. 0.024 L of 0.09 M lithium hydroxide (LiOH) solution wastransferred into a conical flask and titrated with 0.12 M solutionof HCl. Indicate how many mL of HCl must be added to the lithiumhydroxide solution to reach the equivalence. Show all working out.[2 marks]
b. 0.21g of calcium hydroxide Ca(OH)2 are dissolved in 40mLsolution. Determine the concentration and the pH of the solution.Show all working out. [6 marks]
c. 0.85 L of 0.5 M solution of formic acid (HCOOH) is diluted toa volume of 1.42 L with water. Calculate the concentration and pHof the diluted solution (Ka of HCOOH = 1.8 x 10-4). Show allworking out.
