2017-8-24 · Ammonia cannot attack copper metal itself. It reacts only with copper ions in the +2 oxidation state (cupric). In the feedwater loop, these will be in the form of cupric oxide (CuO) and hydroxide (Cu(OH) 2). The cupric state can only form if oxygen is present. So it is the coination of ammonia AND oxygen that is aggressive to copper alloys.
