Given that the K sp for CaF2 at 25°C is 3.9 × 10–11, will a precipitate form when 0.10 L of 2.3 × 10–4 M CaCl2 is added to 0.50 L of 5.0 × 10–3 M NaF? Assume volumes are additive. Please help me I have no clue where to start. Thanks!

The pH of a solution prepared by mixing 55.0 mL of 0.183 M KOH and 10.0 mL of 0.145 M HC2H3O2 is ________. the answer is 13.122 however when i try to plug it into the Henderson Hasselbalch equation (pH= -log(1.8E-5)+log( 0.010065/0.00145) i am not getting...

Do I use 0.100m as x in the equation PE=1/2 kx^2?? Thats all I am confused about. Thanks!

Nevermind I was correct, no need to answer this question.

Please solve the question
