Question

$1000$ g $CaC{O}_3$ solution contain $10$ g carbonate. The concentration of solution as carbonate is :

• A. $10$ ppm
• B. $100$ pm
• C. $1000$ ppm
• D. $10000$ ppm

Answer 1

The correct option is D $10000$ ppm

$1000$ g $CaC{O}_3$ solution contains $10$ g carbonate.
Therefore, ${10}^6$ solution contains $10000$ g $CaC{O}_3$, so concentration of carbonate is $10,000$ ppm.
