Question

At 25 $degree$ C , the hydroxyl ion concentration of a basic solution is 6.75 × 10^–3M .Then the value of Kw is

$13.5 \times 10^{- 6} M^{2}$
$13.5 \times 10^{- 12} M^{2}$
$13.5 \times 10^{- 8} M^{2}$
$10^{- 14} M^{2}$

The correct answer is: $10 to the power of negative 14 end exponent M to the power of 2 end exponent$
