Question

Consider a 0.91 M solution of each of the following salts. will each solution be acidic neutral of basic:
ch3ch2nh3oi
(ch3)3nhi
nh4ch3coo
Rbch3coo

Answer 1

1) CH3CH2NH3+   ----------------------> CH3CH2NH2 + H+ . so it is acidic salt

2) (CH3)3NH+ --------------------> (CH3)3N   + H+ . it is releasing H+ ion so it is also acidic salt

3) CH3COONH4+ ----------------------> neutral

because it is the salt of weak acid CH3COOH and weak base NH4OH

4) CH3COORb ---------------------> it is basic salt

because anion participate in hydrolysis gives basic nature to the solution

CH3COO- + H2O --------------------> CH3COOH + OH-
