Current Question (ID: 21193)

Question:

$\text{Balance the following chemical equation and choose the option with the correct set of values of } x, y, z, \text{ and } p:$ $x\text{Cl}_2 + y\text{OH}^- \rightarrow z\text{Cl}^- + p\text{ClO}^-$

Options:

1. $x = 1, y = 2, z = 2, p = 1$
2. $x = y = z = p = 1$
3. $x = 1, y = 1, z = 2, p = 1$
4. $x = 1, y = 2, z = 1, p = 1$

Solution:

$\text{After balancing change in oxidation state,}$ $2\text{Cl}_2 \rightarrow 2\text{Cl}^- + 2\text{ClO}^-$ $\text{Next, balance 'O' atoms,}$ $2\text{Cl}_2 + 4\text{OH}^- \rightarrow 2\text{Cl}^- + 2\text{ClO}^- + 2\text{H}_2\text{O}$ $\text{Simplifying to get simplest ratios,}$ $\text{Cl}_2 + 2\text{OH}^- \rightarrow \text{Cl}^- + \text{ClO}^- + \text{H}_2\text{O}$ $x = 1, y = 2, z = 1, p = 1$ $\text{Hence, option 4 is the correct answer.}$
