Write ONLY ONE Net ionic equation for each of the following reactions. Give state only for solids, weakly dissociated or gases. No state is required for aqueous solutions. Rules sufficient for judgment which salts are soluble or insoluble: All Na , K and NO3 - salts are well soluble. Please do any preparative work on a scratch paper, so that only ONE equation will be placed in the space highlighted in yellow. Start writing in the position of the arrow to be within yellow space.
