Iindlela zokuChonga iCalcium Formate
I-ion ye-Formate: Bukela ubunzima be-0.5g yesampuli ye-Calcium formate, uyinyibilikise kwi-50ml yamanzi, yongeza i-5ml yesisombululo se-sulfuric acid, uze ufudumale; kufuneka kukhutshwe ivumba elibonakalayo le-formic acid.2.2 I-ion ye-Calcium: Bukela ubunzima be-0.5g yesampuli, uyinyibilikise kwi-50ml yamanzi, yongeza i-5ml yesisombululo se-ammonium oxalate; kuya kubakho i-precipitate emhlophe. Yahlula i-precipitate: ayinyibiliki kwi-glacial acetic acid kodwa iyanyibilika kwi-hydrochloric acid.
Kutheni ukhetha i-calcium formate? Ayinathuli, isebenza ngokukhawuleza, kwaye isebenza imimangaliso kuyo yonke into ukusuka ekutyeni kwezilwanyana ukuya kwizixhobo zokwakha—akukho ngxaki kumgangatho!
