Rita has a solid Ca(OH)2 and also has 2 solutions, namely; 500 mL HF solution with a concentration of 0.02 M and 500 mL of 0.0005 M. Ca(OH)2 solution Rita wants to make a Buffer solution with a pH of 5.48 around 100 mL (assume there is no change in volume), a. Calculate the pH of Rita's solution of HF and Ca(OH)2? b. If Rita wants to make a buffer solution using 100 mL of the HF solution, how many grams of Ca(OH)2 must be added? c. If using the existing Ca(OH)2 solution, how many mL of Ca(OH)2 solution should Rita add?
