Does anyone know the science behind the foam produced by a campden tablet dissolved in water and then boiled?
For example, dissolving a campden tablet in a gallon of water and boiling it will produce the foam.
Maybe the more campden used per volume of water the more foam is produced?
What is the white foam that forms?
What is it comprised of?
Why or how does it form?
Is it safe to leave in a beer?
I know campden tablets are used in chlorine/chloramine removal and sanitation but what is the raison d'être of the foam?
