You start with a 150 mL solution of unknown weak monoprotic acid (HA). a) After adding 100 mL of 0.150 M NaOH, you find half the weak acid is now deprotonated. Given that, what was the concentration of the weak acid prior to adding the NaOH? b) After adding the 100 mL of 0.150 M NaOH to consume half the weak acid, the pH of the solution was 4.22. What was the pH of the solution before adding the NaOH?...

1) A solution of a weak monoprotic acid of unknown concentration was titrated with 0.23 M NaOH. If a 100.-mL sample of the acid solution required exactly 10. mL of the NaOH solution to reach the equivalence point, what was the original concentration of the weak acid? 2) During the titration on problem (2B), after 5.0 mL of NaOH addition, the pH = 3.68. What is the Ka of the weak acid? please show steps i have an exam tomorrow
