Question

part a
which of the ionic compounds shown below will be soluble in water?
view available hint(s)
ag2co3
agcl
na2so4
fe(oh)3

Explanation:

Step1: Recall solubility rules

Salts of sodium ($Na^+$) are generally soluble in water.

Step2: Analyze each option

• $Ag_2CO_3$: Carbonates of silver are insoluble.
• $AgCl$: Chlorides of silver are insoluble.
• $Na_2SO_4$: Sodium salts are soluble, so this is soluble in water.
• $Fe(OH)_3$: Hydroxides of iron(III) are insoluble.

Answer:

$Na_2SO_4$
