Phosphoric Acid
Lintho tsa physicochemical:
1. Mokelikeli o bonaletsang o se nang 'mala,Ha o monko o monate
2.Ntho e qhibilihang 42℃; ntlha e belang 261℃.
3.Miscible le metsi ka karo-karolelano efe kapa efe
Storge:
1. Boloka sebakeng sa polokelo se pholileng, se nang le moea o pholileng.
2. Ipolokele hole le mollo le mehloli ea mocheso.
3. Sephutheloana se tiisitsoe.
4. E lokela ho bolokoa ka thoko ho lintho tse tukang habonolo (tse tukang), li-alkalis, le li-powders tsa tšepe tse sebetsang, 'me u qobe polokelo e tsoakiloeng.
5. Sebaka sa polokelo se lokela ho hlomelloa ka lisebelisoa tse loketseng ho ba le ho lutla.
