2. By giving two examples define the followina
terms:
(a) Hydrated substance
(b) Anhydrous substance
(C) Hygroscopic substance
Answers
Answer:
anhydrous compound (an anhydrate) is a compound with no water in its structure. After water is removed from a hydrate, it becomes an anhydrate. The water molecules are removed by suction or heating the compound to a high temperature. For example, an anhydrous salt has had water driven out from its crystals
HERE IS YOUR ANSWER-
1)hlo In chemistry, a hydrate is a substance that contains water or its constituent elements. The chemical state of the water varies widely between different classes of hydrates, some of which were so labeled before their chemical structure was understood. EG- WATER
2)Anhydrous literally means "no water." In chemistry, substances without water are labeled anhydrous. ... For example, gaseous ammonia is called anhydrous ammonia to distinguish it from its aqueous form. Gaseous hydrogen chloride is called anhydrous hydrogen chloride to distinguish it from hydrochloric acid.
3)Hygroscopy. A hygroscopic substance is one that readily attracts water from its surroundings, through either absorption or adsorption. Examples include honey, glycerin, ethanol, methanol, concentrated sulfuric acid, and concentrated sodium hydroxide (lye).
