Answer 1

(5.) when Nha I dissolues in water it will produce Audic solution. Explanation NH4I - H, O + NH4 OH + R** I . NH4OH being neak base, remains undissociated in aqueous solution. How ever HI being a strong and dissociated into Ht and I cous. Thus, the concentration of H+ ions is greater than of cous. Therefore the solution becomes acidic.
