Current Question (ID: 9193)

Question:

$\text{A Brine solution on electrolysis will not give :}$

Options:

1. $\text{NaOH}$
2. $\text{Cl}_2$
3. $\text{H}_2$
4. $\text{O}_2$

Solution:

$\text{Hint: Brine is a high-concentration solution of salt (NaCl) in water (H}_2\text{O)}$ $\text{Explanation:}$ $\text{Three important chemicals, NaOH, Cl}_2\text{, H}_2\text{, can be obtained by electrolyzing an aqueous NaCl solution (brine).}$ $\text{The reaction is as follows:}$ $\text{NaCl(aq)} \xrightarrow{\text{H}_2\text{O}} \text{Na}^+(\text{aq}) + \text{Cl}^-(\text{aq})$ $\text{At cathode :}$ $\text{H}_2\text{O} + \text{e}^- \rightarrow \frac{1}{2}\text{H}_2\text{(g)} + \text{OH}^-\text{(aq)}$ $\text{At anode :}$ $\text{Cl}^-\text{(aq)} \rightarrow \frac{1}{2}\text{Cl}_2\text{(g)} + \text{e}^-$
