A) 7

NaOH+HCl→NaCl+H2ONaOH+HCl→NaCl+H2O

Sodium chloride is a salt (also known as “salt”, “table salt”, “common salt”) that can be considered as to have been formed due to the reaction of NaOHNaOH and HClHCl - one a strong base, the other a strong acid.

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

Since it’s neutral, it doesn’t really affect the [H+][H+] and [OH−][OH−] in water and its concentration doesn’t alter the pHpH of its solution. So, 7.

OR

NaCl is a salt made from the neutralisation reaction of NaOH and HCl, both of which are strong electrolyte. Therefore NaCl is a neutral salt I.e. there is no acidic or basic character in the salt.

Therefore when dissolved in water, it doesn't change the pH of the solution.
