Solutions

Expert Solution

Acid buffer solution: A mixture of weak acid and it's salt with strong base .

                                        HF + KF, CH3COOH + CH3COONa , HCN + NaCN

Bacid buffer solution: A mixute of weak base and it's salt with strong acid.

                                     NH3+ NH4Cl, NH3 + NH4NO3

0.30 M acetic acid + 0.27 M sodium acetate   ( it is acid buffer solution)

0.34 M ammonium nitrate + 0.38 M ammonia   ( it is basic buffer solution)

0.15 M hydrocyanic acid + 0.12 M sodium cyanide ( it is acid buffer solution)

0.16 M potassium fluoride + 0.23 M hydrofluoric acid ( It acid buffer solution)
