Answer 2

Answer:

$\huge\underbrace\bold\red{Answer}$

Explanation:

Correct option is D

Correct option is DAs we know, pH=−log[H+]

75mL of (M/10)HCl+25mL of (M/10)NaOH

75mL of (M/10)HCl+25mL of (M/10)NaOHSo, pH=−log

75mL of (M/10)HCl+25mL of (M/10)NaOHSo, pH=−log 100

75mL of (M/10)HCl+25mL of (M/10)NaOHSo, pH=−log 100 =2−log5=2−0.698=1.3
