Predict if the solutions of the following salts are neutral, acidic or basic:

NaCl, KBr, NaCN, NH₄NO₃, NaNO₂ and KF

(i) NaCl is neutral as it is salt of strong acid(HCl) and strong base(NaOH)

(ii)KBr is neutral as it is salt of strong acid(HBr) and strong base(KOH)

(iii) NaCN is basic as it is a salt of strong base(NaOH) and weak acid(HCN)

(iv) NH₄NO₃ is acidic as it a salt of strong acid(HNO₃) and weak base (NH₄OH)

(v) NaNO₂ is basic as it a salt of strong base(NaOH) and weak acid(HNO₂)

(vi) KF is basic as it is salt of strong base(KOH) and weak acid(HF)
