For natrium chloride, $p H ≅ 7$ $pH~=7$

Explanation:

Solutions of $N a C l$ $NaCl$ are $p H$ $pH$ neutral. The is the salt of a strong acid and a strong base. Salts of weak acid, for instance, $N a F$ $NaF$ (and note that $H F$ $HF$ is a fairly weak acid), give an alkaline solution in water:

$F^{-} (a q) + H_{2} O (l) \to H F (a q) + H O^{-}$ $F^(-)(aq) + H_2O(l) rarr HF(aq) + HO^-$

The conjugate base of a weak acid, demonstrably competes for the proton.

And likewise such salts as $H S O_{4}^{-} N a^{+}$ $HSO_4^(-)Na^(+)$ , sodium bisulfate, would give acidic solutions.
