Statement-1: When `CO_(2)` is passed through lime water, it first turns milky and then the solution beocmes clear when the passage of `CO_(2)` is continued.
Statement-2: The milkiness is due to the formation of insoluble `CaCO_(3)` which then changes to soluble `Ca(HCO_(3))_(2)` when excess of `CO_(2)` is present.
