Stoichiometry question
« on: September 18, 2010, 09:17:43 PM »
How many hydroxide ions would be produced from the dissociation of 2 moles of aluminum hydroxide?

Please don't give me the answer. Please show me how to get the equation, and I'll try to go from there.

Well how many mols of hydroxide ions will be produced from the dissociation of 1 mol of aluminum hydroxide?

But what is dissociation? Does aluminum hydroxide react with something to dissociate?

It says that Aluminum hydroxide is supposed to react with a solvent, like water. So would the equation be Al(OH)3 + H2O = ?OH + Al + H2O

Al(OH)3 + H2O = ?OH + Al + H2O

Can't you see water cancels out? It is necessary for the dissociation, but technically it is not reacting.

Please don't ignore charges.
