Question

Consider the following: [CH₃NH₃][C₆H₅COO], NaCH₃COO, and NH₄NO_{3. Find if the cation is basic, acidic, or neutral. Find if the anion is basic, acidic or neutral. Find if the aqueous solution as a whole is basic acidic or neutral.}

Answer 1

CH3NH3⁺ : Acidic

C6H5COO^- : basic

NaCH3COO : basic solution

NH4NO3 = acidic solution

Explanation

i) CH3NH3⁺ is partly dissocite and give H3O⁺ in H2O ,so,this cation is acidic

CH3NH3⁺ (aq) + H2O(l) <------> CH3NH2(aq) + H3O⁺(aq)

¡¡) C6H5COO^- is partly hydrolysed by water and gives OH^- , so , this anion is basic

C6H5COO^-(aq) + H2O(l) <------> C6H5COOH(aq) + OH^-(aq)

iii) NaCH3COO dissociate into Na⁺ and CH3COO^- and CH3COO^- partly hydrolysed by water to give OH^-. So, solution of NaCH3COO will be basic.

iv) NH4NO3 dissociates into NH4⁺ and NO3^- ions and NH4⁺ partly dissociates to give H3O⁺ ions.So, solution of NH4NO3 will be acidic.
