(Page créée avec « <br>Think about that you have a flask crammed with water, and a choice of substances that you will check to see how well they dissolve in it. The first substance is desk salt, or sodium chloride. This ionic compound dissolves readily in water. The tip consequence, then, is that instead of sodium chloride crystals, now we have particular person sodium cations and chloride anions surrounded by water molecules - the salt is now in resolution. And, given below [https... ») |
