Q.

How many litres of CO2 at STP will be formed when 500 ml of 0.1M H2 SO4 reacts with excess of Na2 CO3?

View Answer

Correct choice: A

Explanation:

moles of H2SO4 in solution = MX Vin lit =0.1 X500/1000 )=0.05
Na2CO3 + H2SO4→ Na2SO4 + H2O + CO 2
1mole of sulphuric acid gives 1mole i.e 22.4 lit of CO2
0.05 moles of sulphuric acid gives 0.05X22.4 = 1.12 lit of CO2
