Question

A scientist adds a solution of HCl (aq) to a buffer comprised of CH3COOH (aq) and CH3COONa (aq). Which net ionic reaction would initially occur?

Answer 1

Step-by-step explanation:

Net ionic between HCl and the buffer equation

CH3COOH --> acetic acid, CH3COO- acetate , H+ proton from HCl

there is neutralization of the acetate, and an increase in acid

the ionic equation

CH3COO-(aq) + H+(aq) + Cl-(aq) --> CH3COOH(aq) + Cl-(aq)

Net ionic:

CH3COO-(aq) + H+(aq) --> CH3COOH(aq).
