Balance the following equation. Then determine the mole ratio of Ca(OH)2:Al(OH)3. Al2(SO4)3 + Ca(OH)2 Al(OH)3 + CaSO4

Respuesta :

To balance the reaction, we look at the number of atoms of each element we have. It should be equal for both sides. The balanced reaction is:

Al2(SO4)3 + 3Ca(OH)2 =  2Al(OH)3 + 3CaSO4

The ratio of calcium hydroxide and aluminum hydroxide is 3:2.
