Question

Predict if the solutions of the following salts are neutral, acidic or basic: NaCl, KBr, NaCN, NH4NO₃, NaNO₂ and KF 

Answer 1

Answer: We have

(i) NaCl: 

Therefore, it is a neutral solution. 

(ii) KBr:

Therefore, it is a neutral solution. 

(iii) NaCN: 

Therefore, it is a basic solution. 

(iv) NH4NO3 

Therefore, it is an acidic solution. 

(v) NaNO2 

Therefore, it is a basic solution. 

(vi) KF 

Therefore, it is a basic solution.
