Question

What is the natural source of $N{a}_{2}C{O}_3$?

• A. Nitre
• B. Chile salt peter
• C. Dolomite
• D. Trona

Answer 1

The correct option is D Trona

Sodium carbonate is the chemical name for washing soda or soda ash. The major source of soda ash is trona ore.

Trona (trisodium hydrogendicarbonate dihydrate also sodium sesquicarbonate dihydrate);

$N{a}_3\left(C{O}_3\right)\left(HC{O}_3\right).2H_{2}O$ is a natural source of $N{a}_{2}C{O}_3$.
Chile saltpeter: $NaN{O}_3$
Dolomite: $CaMg(C{O}_3{)}_2$
Nitre: $KN{O}_3$
