Sodium hydroxide reacts with sulphuric acid

If you want to know what happens when sodium hydroxide reacts with sulphuric acid and what are the products, then we are going to discuss sulfuric acid and sodium hydroxide reaction.

 

Sodium hydroxide is a strong base and sulphuric acid is a strong acid.

Sodium hydroxide reacts with sulphuric acid to produce sodium sulphate and water. neutralisation reaction takes place,

 

Following is the neutralisation reaction of sulphuric acid and sodium hydroxide

 

`NaOH + H_2SO_4 → Na_2SO_4 + 2H_2O`

 

 

Sodium ions (`Na^+`) and hydroxyl ions(`OH^-`) are formed from sodium hydroxide and hydrogen ions(`H^+`) and sulphate ions (`SO_4^ (2-) `) are formed from sulphuric acid.

 

`NaOHrightarrowNa^+      + OH^-`

`H_2SO_4\rightarrow\ H^+  +     SO_4^{2-}`

 

 

Hydrogen ions combine with hydroxyl ions to produce water and sodium ions combine with sulphate ions to produce sodium sulphate.

 

`Na^+     + SO_4^(2-)\rightarrow Na_2SO_4`

`H^+     +     OH^(-)     \rightarrow    H_2O`

 

So, sodium sulphate (a salt) and water are the products when sodium hydroxide reacts with sulphuric acid. The reaction is neutralisation reaction.

This reaction is highly exothermic, which means it releases a lot of heat.
