When the hydrogen ion concentration $[H^{+}]$ changes by a factor of $1000$ , the value of $pH$ of the solution

Answer:

Solution:

Let the initial concentration of $H^{+}$ be 1

$∴ [H^{+}] i = 1 \Rightarrow pH = 0$

It changes by 1000 units

$∴ [H^{+}] f = 10^{3} \Rightarrow pH = - 3$

So, pH decreases by 3 units.
