Izindlela Zokuhlonza I-Calcium Formate
I-ion ye-Formate: Kala u-0.5g wesampula ye-Calcium formate, uyincibilikise ku-50ml wamanzi, engeza u-5ml wesisombululo se-sulfuric acid, bese ushisa; kufanele kukhishwe iphunga elihlukile le-formic acid.2.2 I-ion ye-Calcium: Kala u-0.5g wesampula, uyincibilikise ku-50ml wamanzi, engeza u-5ml wesisombululo se-ammonium oxalate; kuzokwakheka i-precipitate emhlophe. Hlukanisa i-precipitate: ayincibiliki ku-glacial acetic acid kodwa incibilika ku-hydrochloric acid.
Kungani kufanele ukhethe i-calcium formate? Ayinawo uthuli oluningi, isebenza ngokushesha, futhi isebenza izimanga kukho konke kusukela ekudleni kwezilwane kuya ezintweni zokwakha—akukho ukuyekethisa kwikhwalithi!
