Question

When Soduim carbonate solution is added to magnesuim sulpahte solution,the following reaction takes place :

${\text{MgSO}}_2+{\text{Na}}_2{\text{CO}}_3\to {\text{MgCO}}_3+{\text{Na}}_2{\text{SO}}_4$

The reactant(s) in the reaction is/are:

• A. ${\text{MgSO}}_2$
• B. ${\text{Na}}_2{\text{CO}}_3$
• C. ${\text{MgCO}}_3$
• D. ${\text{Na}}_2{\text{SO}}_4$

Answer 1

Answer: (A), (B)

The correct options are
A ${\text{MgSO}}_2$
B ${\text{Na}}_2{\text{CO}}_3$

A reactant is a substance that takes part in and undergoes the chemical reaction whereas a product is a substance that is formed as the result of a chemical reaction. Reactants are written on the left side of the arrow.

The reactants in the given reaction are magnesium sulphate ${\text{MgSO}}_2$ and sodium carbonate ${\text{Na}}_2{\text{CO}}_3$
