Chromium nitrate acid or base
WebNow, suppose the chromium(III) nitrate is reacting as a solid, giving this equation with state symbols: ... Boric acid is a weak acid. NH 4 OH is a weak base. The total ionic is this: H 3 BO 3 (aq) + 3NH 4 OH(aq) ---> 3NH 4 + (aq) + BO 3 3 ¯(aq) + 3H 2 O(ℓ) 3) The above is also the net ionic. This is because there are no spectator ions.
