Calcium oxide (CaO) is used as dry- ing agent in the preparation of Am- monia in laboratory. Can concen- trated `H_2SO_4` be used as drying agent instead of CaO? Justify your answer.

Verified by Experts

No con `sulphuric acid` can not be used as drying agent here. Because ammonia is basic and it will react with sulphuric acid. To avoid this, CaO is used as drying agent.

Sulphuric acid is considered as the king of chemicals: The prosperity of any country is measured by the annount of sulphuric acid it consumnes. Sulpliuric acid is, thus, a substance of very great commercial importance as it is used practically in every important industry. This is due to the following properties of sulphuric acid: a) acidic nature b)oxidising nature c) dehydrating nature - d) sulphonation Concentrated H_2 SO_4 cannot be used to prepare HBr or HI from KBr or KI because it:

If an element is in its highest possibel oxidation state in a compound, it can act as an oxidising agent. If an element is in its lowest possible oxidation state in a compound, if can act as reducing agent. If an element is in the intermediate oxidation state in a compound, it can serve as both oxidising and reducing agent. Based on the above three guidelines, classify the following compounds into three categories and post them in the table given below. KMnO_4 , H_2O_2 , H_2C_2O_4 , FeSO_4 , HCIO_4 , SO_2 , Na_2S_2O_3 , K_2Cr_2O_7
