Question

What are the solution beahviours of `"aluminum hydroxide"`, and `"sodium carbonate"`?

Answer 1

Well aluminum hydroxide is a bit of a non-starter.....`Al(OH)_3` is an soluble as a brick.

Explanation:

But `"sodium carbonate"` speciates in aqueous solution according to the following equation....

`Na_2CO_3(s) stackrel(H_2O)rarr2Na^+ + CO_3^(2-)`

And carbonate ion, is a weakish base.....

`CO_3^(2-) + H_2O(l) rightleftharpoons HCO_3^(-) + HO^-`

The equilibrium lies to the LEFT as you face it.

Aluminum hydroxide would tend to precipitate out as alumina, `Al_2O_3`

`2Al(OH)_3(aq) rarr Al_2O_3+3H_2O`
