A sample of calcium carbonate is 80% pure, 25 gm of this sample is treated with excess of HCl .How much volume of `CO_(2)` will be obtained from at 1 atm & 273 K ?

Text Solution

Verified by Experts

100 g of impure calcium carbonate contain
=80 g pure calcium carbonate
25 g of impure calcium carbonate sample contain
` = 80/100 xx 25`
= 20 g pure calcium carbonate
The desired equation is :
`{:(CaCO_(3) + 2HCl,to,CaCl_(2) + CO_(2) + H_(2)O),(1 mol ,,22.4 "litre"),(100g ,,"at NTP"):}`
100 g pure `CaCO_(3)` liberate = `22.4" litre " CO_(2)`
