A friend of mine was talking to me about drinking "Lime Phosphates" as a kid in a soda shop. I googled this, and it seems that soda jerks would put a drop of phosphoric acid in the soda for bite. I'm curious to try this with my soda setup. Does anyone know the concentration used for a glass of soda? I've seen phosphoric acid in 10% concentrations and in 85% concentrations.
Thanks,
Matt
