Question

What ions are present in a solution of sodium carbonate. Write the formulas for the ions and indicate the ratio they are present in

Answer 1

Sodium carbonate is Na₂CO₃

_{It is soluble in water and it will dissociate into the component ions.}

Na₂CO₃ ===> 2Na⁺ + CO₃^2-

So, the ions present are 2 sodium ions (Na⁺) and 1 carbonate ion (CO₃^2-)
