How do i write the net ionic equation for the following balanced molecular equation?

Cu(OH)2 solid + 2HClO4 ---->>Cu(ClO4)2 aqueous + 2H2O liquid im confused on what to do for the net ionic because i thought you couldn't split solids into their ions(dissociate them) so if you can't split them i can't just write 2H+ ---->> 2H2O liquid please give me the net ionic and explain why that is the answer

Perchloric acid (HClO4) is aqueous so when this is added to the copper (II) hydroxide (Cu(OH)2) it does dissociate into Cu+2 and 2OH- ions. The net ionic equation is 2H+ + 2OH- Rightwards Arrow

2H2O.

P.S. you can also write Cu(ClO4)2 aq as Cu+2 and 2ClO4-. I prefer this notation because the aqueous ions are not actually together and this way aqueous is implied - you dont have to write "aq."

You do not specify the concentration of perchloric acid. If you are using concentrated acid, it will probably decompose into hot HCl acid and lots of O2 gas. This is very dangerous!! Do not try this!
The copper hydroxide will catalyze the decomposition. The competing reactions and the insolubility of copper hydroxide will make this at best a very minor result Le Chatlier Principle). If your are wanting to make copper perchlorate - use cold copper sulfate and cold perchloric acid. Most perchlorates are very soluble. Ammonium perchlorate would be safer still.
