Question

The pH of a solution is increased from 3 to 6. its H+ ion concentration will be
(a) reduced to half
(b) doubled
(c) reduced by 1000 times
(d) increased by 1000 times

Answer 1

answer : option (c) reduced by 1000 times.

explanation : we know, pH is given by $pH=-log[H^+]$
where $[H^+]$ is the concentration of hydronium/ hydrogen ions.

now, if pH = 3 ,

3 = -log$[H^+]$

$[H^+]$ = 10^-3

if pH = 6,

6 = -log$[H^+]$

$[H^+]$ = 10^-6

hence, it is clear that, when pH increases 3 to 6, concentration of H+ ions reduced by 1000 times.

hence, option (c) is correct.
