Calculate the percent weight loss suffered by sodium bicarbonate on strong heating? 

Text Solution

Verified by Experts

On strong heating sodium bicarbonate decomposes and loses carbondioxide and water.
`2NaHCO_(3)rarrNa_(2)CO_(3)+H_(2)O+CO_(2)`
2moles of `NaHCO_(3)` = (44+18) grams weight loss = 62 gms weight loss
100 grams of `NaHCO_(3)` = ?
The percent weight loss suffered by sodium carbonate on calcination=` (100)/(2xx84)xx62 = 36.9%`
