Correct (R): In such very dilute solutions both source of H ⊕ ions from HCl and H 2 O must be considered and due to common ion ( H ⊕) supression of ionization occurs

Q. Statement 1 : pH of $1 0^{- 8} M H Cl$ is not equal to 8
Statement 2 : $H Cl$ does not dissociate property in very dilute solution

Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1

Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1

Statement 1 is True, Statement 2 is False

Statement 1 is False, Statement 2 is True

Correct (R): In such very dilute solutions both source of $H^{\oplus}$ ions from $H Cl$ and $H_{2} O$ must be considered and due to common ion $(H^{\oplus})$ supression of ionization occurs
