MCQ
The ${H^ + }$ ion concentration is $1.0 \times {10^{ - 6}}$ mole/litre in a solution. Its $pH $ value will be
  • A
    $12$
  • ✓
    $6$
  • C
    $18$
  • D
    $24$
✓

Answer

Correct option: B.
$6$
(b) $[{H^ + }] = 1.00 \times {10^{ - 6}}$ mole/litre

$pH = - \,\log \,\,[1.00 \times {10^{ - 6}}]$;  $pH = 6.$
