Calculate the pH of a 1.8 M solution of NaI

Question

Question

Answer 1

Answer #1

HI + NaOH NaI + H₂O

(SA) (SB) (Neutral salt)

Since, the salt is formed from a strong acid and a strong base, they do not hydrolyse and the pH of the solution remains neutral (pH = 7).

Also, NaI undergoes electrolysis to give the neutral ions Na⁺ and I^- . So, the pH of the solution is 7.

NaI Na⁺ + I^-
