To solve the problem of finding the amounts of NaOH and Na2CO3 in a mixture that was titrated with HCl, we will follow these steps: ### Step 1: Understand the Reaction The titration involves NaOH and Na2CO3 reacting with HCl. The balanced chemical reactions are: 1. NaOH + HCl → NaCl + H2O (1:1 ratio) 2. Na2CO3 + 2HCl → 2NaCl + H2O + CO2 (1:2 ratio) ### Step 2: Set Up the Equations ...
