Question 66

Aluminium hydroxide reacts with dilute sulfuric acid to form aluminium sulfate solution and water.

Complete the balanced equation for the reaction by adding a number in front of H2O(l)\text{H}_2\text{O}(\text{l})H2​O(l).

2Al(OH)3(s)+3H2SO4(aq)→Al2(SO4)3(aq)+………H2O(l) 2\text{Al(OH)}_3(\text{s}) + 3\text{H}_2\text{SO}_4(\text{aq}) \rightarrow \text{Al}_2(\text{SO}_4)_3(\text{aq}) + \dots\dots\dots\text{H}_2\text{O}(\text{l}) 2Al(OH)3​(s)+3H2​SO4​(aq)→Al2​(SO4​)3​(aq)+………H2​O(l)
