Question

25ml of 0.150ml M hydrofluoric acid, HF, is titrated with 0.100 M potassium hydroxide. A. what is the pH of the acid initially (before any is added.) B. what lume of potassium hydroxide must be added to reach the equivalence point. C. what is the pH of the solution at the halfway point of the titration(halfway to the equivalence point) D. what is the pH of the solution at the equivalencepoint. E. plot the titration point. make sure there is enough data. F. what indicator wouldyou use for this titration. what color change would you observe.

Explanation / Answer

THIS WILL HELP YOU

The acid dissociation constant, Ka, of butanoic acid (C3H7COOH) is defined as:
Ka = [H+][C3H7COO-]/[C3H7COOH]
Since the amount of acid that dissociates is very small in comparison to the
original amount, we can simplify to say: Ka = [H+]
