AI Generated Solution

To solve the problem, we need to determine the amount of KOH present in a mixture solution of KOH and Na2CO3 based on the titration data provided. ### Step-by-Step Solution: 1. **Understanding the Reaction with Indicators**: - When KOH is titrated with HCl using phenolphthalein, it requires 15 mL of (N/20) HCl. - When Na2CO3 is titrated with HCl using methyl orange, it requires 25 mL of (N/20) HCl. - The difference in volume indicates how much HCl is reacting with Na2CO3. ...
