प्रश्न
Explain, why (or give reasons for)
In the preparation chloride from sodium chloride, the gas can be obtained below 200°C or above. But the lower temperature is preferred.
उत्तर
Lower temperature is preferred because at higher temperature sodium sulphate forms a hard crust and sticks to the bottom of the flask and is difficult to remove.
