Ca2+(aq) + 2C17H35COO-(aq) ? Ca(C17H35COO)2(s). The precipitate is also create verbally as (C17H35COO)2Ca Mg2+(aq) + 2C17H35COO- (aq) ? Mg(C17H35COO)2 (s) Qualitative: senior high levels of Ca2+ and Mg2+ ions make the water hard. This means soap doesnt welt (form froth). Sydney water is identified as soft water as its hardness lies between 10 40 ppm. Soft water: < 75 ppm Hard water: one hundred liter 500 ppmIf you want to brook a full essay, assign it on our website: Ordercustompaper.com
