Uburyo bwo kumenya foromate ya kalisiyumu
Iyoni ya Formate: Pima garama 0.5 z'icyitegererezo cya Calcium formate, uyishongeshe muri mililitiro 50 z'amazi, ongeramo mililitiro 5 z'icyitegererezo cya aside sulfurike, hanyuma ushyuhe; impumuro idasanzwe ya aside formic igomba gusohoka.2.2 Iyoni ya Calcium: Pima garama 0.5 z'icyitegererezo, uyishongeshe muri mililitiro 50 z'amazi, ongeramo mililitiro 5 z'icyitegererezo cya ammonium oxalate; hazavuka umwuka wera. Gutandukanya umwuka: ntushobora gushonga muri aside glacial acetic ariko ushobora gushonga muri aside hydrochloric.
Kuki wahitamo formate ya kalisiyumu? Ifite ivumbi rike, ikora vuba, kandi ikora ibitangaza muri byose kuva ku biryo by'amatungo kugeza ku bikoresho by'ubwubatsi—nta kibazo ku bwiza bwayo!
