Sorry, I should have been more specific.
Where there any precipitates with them? I know that all three should end up being neutral.
Well, here's a crack at it.
CaCO
3 + H
+ + Cl
- -----> CaCl
2 + OH
- + 1/2 O
2One mole of calcium carbonate reacts with one mole of HCl to produce one mole of CaCl
2, one mole of hydroxide ions, and 1/2 mole of oxygen gas.
Al(OH)
3 + 3H
+ + 3Cl
-/sup] ------> AlCl3 + 3H2O
One mole of aluminum hydroxide reacts with three moles of hydrochloric acid to produce one mole of aluminum chloride and three moles of water.
Mg(OH)2 + 2H+ + 2Cl- -----> MgCl2 + 2H2O
One mole of magnesium hydroxide reacts with hydrochloric acid to produce one mole of magnesium chloride and two moles of water.
That first one doesn't seem right to me. However, the other two are quite correct.
Actually, none of the three reacts with water.
CaCO3 is insoluble in water.
Quite right. I mistook it with sodium bicarbonate
