104 B. Identifying Hydrates Is Solution of Residue Same Color as Solution of Original Compound? (Y/N) Color and Texture of the Residue after Heating Is the Com pound a Tru Hydrate? (Y/N) Does Water Appear with Heating (Y/N) Color before Heating Compound Being Tested

Answer 1

The given Salt is coll, which exists as hexahydrate, Collzo 6H2O . • Compound Beingtested CoCl₂ •6H20 • Color Before heating : Pale fink as when it is dissolved in water it produces complexion, [COLH2O) 6 ]2+ On heating following equilibria is established [coltolo J2+ +4ct+ Heat ₃ [coclulisho Pink Blue

Does water Appear with Yes Heating • Color and texture of : Blue-color residue after [Coclu] heating • Is solution has same color as of original : No Original: Pink Residue: Blue Compound On heating solution becomes fick due to formation of Coclu But on the cooling, again equilibrid Shifts to left and formation of Pale hink solution appears. These properties are shown by true-hydrates. • Is compound a Yes true heydrate?
