Hi, I was wondering if there is a difference between sodium bisulfite and sodium met abisulfite. Some references on the web say that they are different and some say that they are the same and therefore interchangable in chemical formulae. I've looked up the chemical formula or name for each and they appear different, alth ough I have come across a reference (on a Kodak site) that says that Sodium bisu lfite is simply sodium metabisulfite in solution.
Where is this going, i hear you say. Well, I have all the makings of a PMK brew but have been supplied with sodium metabisulfite instead of sodium bisulfite. I dont know whether to just use the same quantity as in the recipe or whether I have to modify it. I don't really want to waste time and lf film in needless ex periments if I'm not starting off on the right foot.
Thanks in advance for any advice.
Neil.
