What is the pH of a resultant solution produced, when an aqueous solution of $p H$ = 6 is mixed with an equal volume of an aqueous solution of $p H$ = 3.

Options:

Answer:

Solution:

$p H = 6$ means $[H^{+}] = 1 0^{- 6} M$
$p H = 3$ means $[H^{=}] = 1 0^{- 3} M$
After mixing,
Total $[H^{+}] = \frac{(1 0^{- 6} + 1 0^{- 3})}{2} = \frac{1.001 \times 1 0^{- 3}}{2}$ $= 5.005 \times 1 0^{- 4}$
$p H = 4 - l o g 5.005; p H = 3.301$ .
