Write a balanaed chemical equation for each of the following:
Action of heat on aluminium hydroxide

Text Solution

Verified by Experts

Magnesium chloride hexahydrate on heating first forms a basic chloride which on further heating decomposes to form magnesium oxide.
`MgCl_(2).6H_(2)O overset("heat")rarr underset(("Basic chloride"))(Mg(OH)Cl) + HCL + 5H_(2)O`
`Mg(OH)Cl overset("heat")rarr underset("Magnesium oxide")(MgO + HCl)`
