A@di, sorry, I still don't understand Oct/Nov 2008 Q15 but thanks for the other explanations.By the way, can list down all the important metals/transition metals/non-metals with their colours and their salts' colours?And if Barium nitrate (or any other soluble substance) is soluble, it means we can break it down into it's ions? Therefore, we can say that Barium is formed?
Right, Thanks so much, I understand it all now!!
