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. Chromium(III) nitrate describes several inorganic compounds consisting of chromium, nitrate and varying amounts of water. Most common is the dark violet hygroscopic solid. An anhydrous green form is also known. Chromium(III) nitrate compounds are of a limited commercial importance, finding some applications in the dyeing industry. It is common in academic laboratories for the synthesis of chromium coordination complexes.
