Question

The $pH$ of $0.1M$ $NaCl$ solution is:

• A. 1
• B. 13
• C. 7
• D. zero

Answer 1

Answer: (C)

7

$NaOH+HCl\to NaCl+H_{2}O$

Sodium chloride is a salt that is formed due to the reaction of $NaOH$ (strong base) and $HCl$-( a strong acid).

Strong acids react with strong bases generally give neutral salts, and $NaCl$ is one of them.

Since it’s neutral, it doesn’t really affect the $\left[H^{+}\right]$ and $\left[O{H}^{-}\right]$ in water and its concentration doesn’t alter the pH of its solution. So, the $pH$ is 7.
