Here is question from Uplearn A-Level Chemistry Course.
Hypobromous acid has a Ka of 2.24x10^-9 at room temperature. What is the concentration of hypobromous acid in a solution that has a pH of 6.56?
Here is the formula for Ka:
Ka = [H+][A-]/[HA]
I know how to do this question with a calculator but my mathematics lets me down finding the hydrogen ion concentration from the pH without a calculator. Is this even a question that could appear in the IMAT?
Thanks for your help! Great website!
