AlCl3 + 3H2O = Al(OH)3 + 3HCl; hydrolysis is an endothermic reaction
Thread Content
AlCl3 + 3H2O = Al(OH)3 + 3HCl. Hydrolysis is an endothermic reaction; therefore, the solution becomes acidic after hydrolysis. But can aluminum hydroxide exist in acidic conditions? ? ? Is there also flocculent matter or sediment of aluminum hydroxide? ? I’m not good at chemistry; please give me some advice!
Aluminium hydroxide, with the chemical formula Al(OH)3, is the hydroxide of aluminium. Aluminum hydroxide can react with acids to produce salts and water, as well as with strong bases to produce salts and water; therefore, it is also an amphoteric hydroxide. It is insoluble in water, which is why the aforementioned reactions can take place.
