What is the equation for the reaction between methylamine and sulfuric acid?

Methylamine is a weak base and can neutralize strong acids, such as hydrochloric acid, sulfuric acid, etc. The reaction between methylamine and sulfuric acid can be written as follows:



In this neutralization reaction, 2 moles of methylamine (weak base) react with 1 mole of sulfuric acid (strong acid) and generate 1 mole of a methyl ammonium salt (a salt of a weak base and a strong acid). 


In a similar reaction, methylamine can neutralize hydrochloric acid, another strong acid. The reaction can be written as:



Here, methylamine and hydrochloric acid react with each other and produce a salt, known as N-methyl ammonium chloride. 


It is interesting to note that the salts produced in these reactions, when dissolved in water, generate acidic ions (such as , etc.). 


Hope this helps.
