I brew BIAB. I usually fill my brew kettle the day before brewday. A friend suggested I use Campden tablets and fill the kettle on brewday. Do they get rid of residual chlorine in municipal water?( What I use). And is it Sodium Metabisulphite oe Potassium Metabisulfite?

They do get rid of chlorine and chloramines in tap water. I use it to dechlorinate. A single Campden tablet weighs about 0.3 grams and it will work for 20 gallons of tap water. The amount you're adding yields a trivial amount of chloride and sulfate, not enough to calculate, really. And it doesn't matter, but they can be either potassium or sodium metabisulfite.
Yup, that's the only water chemistry I did for years
