Dear Colleagues,
I've always wondered why we add Conc. Formalin to our Sodium
Acetate/Mercuric Chloride solution immediately before use.?
Is it because it was necessary with Helly's, which used to oxidise and go
off rather quickly - appearing muddy brown etc.?
If we never had to bother with Formal Sublimate, why are we so concerned
with the Sodium Acetate in B5? Is there a reaction?? Or not??
