1.	The following two experiments are conducted to prove the release of carbon dioxide and water vapor due to the burning of candle . Between the two experiments which is correct ?Correct ? Givereasons in support of your answer.
Answer» SOLUTION :The products of the combustion of a candle (mixture of hydrocarbons)are`CO_(2)` andwater vapour . `CO_(2)` can be detected by passing it through LIME water which turns milky . `H_(2)O` can be detected by passing it through anhydrous `CuSO_(4)` which turns blue . if the gaseous mixture`(CO_(2)+H_(2)O)`is passed through anhydrous `CuSO_(4)`first , `H_(2)` Is absorbed by `CuSO_(4)` and the left over gas , that is `CO_(2)` turns lime water milky ,But if the gaseous mixture is passed thouogh lime water first , `CO_(2)` GETS absorbed and along with that water , vapour ALSO gets condensed . Hence , anhydrous `CuSO_(4)` does not turn blue . So , experimental set up - B is INCORRECT.
