If the hydrogen ion concentration of a given solution is 5.5 10^ … - Vidyadip

MCQ

If the hydrogen ion concentration of a given solution is $5.5 \times {10^{ - 3}}\,mol\,\,litr{e^{ - 1}},$ the $pH$ of the solution will be

✓
$2.26$
B
$3.4$
C
$3.75$
D
$2.76$

✓

Answer

Correct option: A.

$2.26$

(a) $[{H^ + }] = 5.5 \times {10^{ - 3}}$ $mole/litre$

$pH = - \log \,\,[{H^ + }]$ ;$pH = - \log \,\,[5.5 \times {10^{ - 3}}]$;$pH = 2.26$
