mL of a mixture of and is titrated with . Which of the following statement(s) is/are correct? — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

**Logic:** Ph endpoint ($V_1$) occurs when all $NaOH$ (if any) and half of $Na_2CO_3$ is neutralized. $V_1 = V_{NaOH} + 1/2 V_{Na_2CO_3}$. <br>MeOH endpoint ($V_2$) occurs when all components are fully neutralized. $V_2 = V_{NaOH} + V_{Na_2CO_3} + V_{NaHCO_3}$. <br>In a mixture of just $Na_2CO_3$ and $NaHCO_3$, $V_{HCl}$ for original $NaHCO_3 = V_2 - 2V_1$.
