PH of strong acids and strong bases

Question

Which of the following solution will have pH closer to 1.0 ?

Moderate

A

100 ml of M/10 HCl + 45 ml of M/10 NaOH
B

55 ml of M/10 HCl + 45 ml of M/10 NaOH
C

10 ml of M/10 HCl + 90 ml of M/10 NaOH
D

75 ml of M/5 HCl + 25 ml of M/5 NaOH

Solution

Following reaction will occur
HCl + NaOH $\to$ NaCl +H₂O
milli
moles
75 x 0.2 25 x 0.2 0 0
t = $t_{\infty}$ 15 - 5 = 10 5 - 5 = 0 0 0
$[H^{+}] = \frac{10 \times 10^{- 3}}{100 \times 10^{- 3}} = 10^{- 1}$
P^H=1
