Question

Which of the following is a buffer solution? Explain your answer.

i) HCl+ NaCl

ii) CH3COOH+ NH4Cl

iii) CH3COOOH + CH3COONa​

Answer 1

Answer:

HCl+ NaCl=NaCl + HCl → NaH + Cl2 - Balanced equation | Chemical Equations online!

CH3COOH+ NH4Cl=

CH3COOOH + CH3COONa=First, because CH3COOH is a weak electrolyte and CH3COONa is a strong electrolyte, the major species in the solution are CH3COOH (a weak acid), Na+ (which is neither acidic nor basic and is therefore a spectator in the acid–base chemistry), and CH3COO– (which is the conjugate base of CH3COOH).
