One gram limestone is heated and quickline so formed is dissolved in one litre of water. The normality of solution is `0.01xx x`. What is value of x.

Text Solution

Verified by Experts

The correct Answer is:
2
`underset("limestone")(CaCO_(3))rarrunderset("Quicklime")(CaOdarr+)CO_(2)uarr`
100 g ________ 56 g
1 g ________ 0.56g
Normality = `(0.56)/(28)xx(1)/(1)=0.02N`
Eq. wt of Quicklime `(CaO)=28`
