So we all know that sodium bisulfite will clear the stain of dichromates and "neutralize" them. But does it actually make the dichromates safer? As in, environmentally neutral and inert.
I ask this mainly because I've been turning my used sensitizer green with the addition of Na-Bisulfite, and then pouring it down the drain (very small amounts).
My question is whether or not this is necessary, or if I'm just wasting Na-bisulfite.
