  • In periodic table group I elements' `(Li^+,Na^+,K^+ etc )` salts are highly soluble.So NaCl is highly soluble.
  • Salts which consists of `NO_3^-` is generally soluble. So `KNO_3` is generally soluble
  • Salts with `Br^-,Cl^-` also have general solubility.So KBr have general solubility.
  • As we know `CO_2` is partially soluble in water.

 

So the greatest solute is NaCl at ` 25^0C`
