State whether 0.1 M solutions of each of the following salts are acidic, basic, or neutral. explain your reasoning for each by writing a balanced net ionic equation to describe the behavior of each non-neutral salt in water: NaCN, KNO3, NH4Cl, NaHCO3, and Na3PO4

Solutions

Expert Solution

NEUTRAL SALT : salt formed by the combination of a strong acid and stong base.

ACIDIC SALT: salt formed by strong cid and weak base

BASIC SALT: salt formed by wak acid and strong base.

1.NaCN + H₂O NaOH + HCN ( this concludes that NaCN salt is formed by weak acid and strong base) so NaCN is a basic salt.

2. KNO₃ + H₂O KOH +HNO₃ ( HNO₃ = strong acid, KOH = strong base) therefore KNO₃ is a neutral salt.

3.NH₄CL +H₂O NH₄OH + HCl (NH₄OH = weak base, HCl=strong acid) and NH₄Cl is a acidic salt

.4.NaHCO₃ + H₂O NaOH +H₂CO₃ ( NaOH =strong base, H₂CO₃=weak base) therefore NaHCO₃ is a basic salt,

5.Na₃PO₄ + H₂O NaOH + H₃PO₄ ( H₃PO₄ = strong acid, NaOH= strong base) therefore Na₃PO₄ is a neutral salt.
