Question

Will a solution of CH3NH3NO3 be acidic, basic or neutral? Explain and justify your answer clearly.

Answer 1

CH₃NH₃NO₃ is a salt produced by the neutralization reaction between methyl amine CH₃NH₂ (a weak base) and nitric acid HNO₃ (a strong acid):

CH₃NH₂ + HNO₃ -> CH₃NH₃NO₃

Salts produced from the reaction between a strong acid and a weak base are acidic salts. So the answer is that CH₃NH₃NO₃ will have an acidic solution.

Remember these rules too (they may come in handy):

Strong acid + strong base = neutral salt

Strong acid + weak base = acidic salt

Weak acid + strong base = basic salt

Weak acid + weak base = depends on which is the stronger
