$P$ $(10 mL $of $0.1 M NaOH +20 mL$ $of 0.1 M $ acetic acid) diluted to $60 mL$ |
$1$ the value of $\left[ H ^{+}\right]$does not change on dilution |
|
$Q $ $(20 mL $ of $ 0.1 M NaOH +20 mL $of $0.1 M $ acetic acid) diluted to $ 80 mL$ |
$2$ the value of $\left[ H ^{+}\right]$changes to half of its initial value on dilution the value of $\left[ H ^{+}\right]$changes to two times of its initial value on dilution |

$R$ $(20 mL $ of $ 0.1 M HCl +20 mL$of $0.1 M$ ammonia solution) diluted to $80 mL$ |
$3$ the value of $\left[ H ^{+}\right]$changes to $1 / \sqrt{2}$ times of its initial value on dilution |

$S$ $10 mL$ saturated solution of Ni $( OH )_2$in equilibrium with excess solid Ni $( OH )_2$ s diluted to $20 mL$ (solid Ni $( OH )_2$ is still present afterdilution). |
$4$the value of $\left[ H ^{+}\right]$changes to $\sqrt{2}$ times of its initial value on dilution |
| $5$ the value of $\left[ H ^{+}\right]$changes to $\sqrt{2}$ times of its initial value on dilution |
Match each process given in $LIST-I$ with one or more effect(s) in $LIST-II$. The correct option is
