AI Thread Summary
The discussion focuses on predicting the acidity or basicity of various salts in aqueous solutions. NH4Cl is identified as acidic due to the formation of HCl, while NaCl and KNO3 are deemed neutral as they do not alter the pH significantly. MgCO3 and NaH2PO4 are classified as basic, producing hydroxide ions in solution. The accuracy of the predictions is acknowledged, but the provided reaction equations are criticized for being incorrect. Overall, the analysis emphasizes the importance of understanding the behavior of salts in water.

Homework Statement


Predict whether an aqueous solution of the following salts will be acidic, basic or neutral. Briefly
explain your results.
a. NH4Cl
b. NaCl
c. MgCO3
d. NaH2PO4
e. KNO3

Homework Equations



The Attempt at a Solution


NH4Cl + H2O --> NH4OH + HCl (acidic)
NaCl + H2O --> NaOH + HCl (neutral)
MgCO3 + H2O --> MgOH + HCO3 (basic)
NaH2PO4 + H2O --> NaOH + H3PO4 (basic)
KNO3 + H2O --> KOH + HNO3 (neutral)
Is this correct?

Good.
 


Predictions are OK, but reaction equations are horrible.
