everyday chemistry - Brewing tea with deionized water


I am wondering what efect brewing tea (let us assume for the sake of simplicity it is green tea, brewed at about 80 °C) in deionized water might have on the product.




  • Will the lack of ions in the water increase or decrease the solubility of alcaloids from the tea leaves. Will the effect be different for alkaloids in salt and alcaloids in amine form?




  • Will drinking moderate amounts of such tea (0.5–1 l per day) detrimentally affect one's electrolyte metabolism? I am guessing maybe it does not matter, since the tea fills the water with electrolytes anyway – but will these electrolytes be significally different from what you would get in tap/mineral water? and if so, will it matter?
