Chemistry Acid/base solubility question

[Nellen2222]

Homework Statement

Each of the following salts can be prepared from an acid and a base. Write the balanced molecular equation and the net ionic equation for the preperation of each. indicate states of the reactants and producys . Review solubility rules if neccesary to determine the solubility of reactants.

Homework Equations

The Attempt at a Solution

a) AgNO3
b)RbClO4
C) Na3PO4

a/ AgOH(s) + HNO3(aq) --> AgNO3(aq) + H2O(aq) (the molecular equation
Net ionic: AgOH + H+ + NO3- ------> Ag+ + NO3- + H2O
Final net ionic after cancellation: AgOH- + H+ ---> Ag+ + H2O

Am I write on this first one? i don't really think I am, I am not confident in it

b/ RbClO4

my attempt: RbOH(s) + HClO4- ----. RbClO4 (aq) + H2O

My attempt at net ionic: RbOH(s) + H+ + ClO4- ---> Rb+ + H2O
Final net ionic after cancellation: RbOH + H+ ---> Rb+ + H2O

Is this right? Please help!

Bump... anyone?

Close, but you need to pay attention to charges - no such thing as AgOH^- (although you wrote it correctly in other places). Also, it won't hurt to mark the fact AgOH is insoluble.

Final net ionic after cancellation: RbOH + H+ ---> Rb+ + H2O

RbOH is well soluble (as opposed to AgOH) and 100% dissociated.
