Download the electronic version of the book: http://bbs.hcbbs.com/thread-13140-1-2.html short answer questions: 1. What is the principle of the lime soda ash method for refining brine?
Lime-soda ash purified brine uses Ca(OH)2 (grey milk) to precipitate magnesium and Na2CO3 to precipitate calcium.
The lime-soda ash method uses Ca(OH)2 (grey milk) to precipitate magnesium and Na2CO3 to precipitate calcium. The chemical reaction is: Mg2++Ca(OH)2→Mg(OH)2↓+Ca2+ Ca2++Na2CO3→CaCO3↓+2Na+
The lime-soda ash method uses Ca(OH)2 (grey milk) to precipitate magnesium and Na2CO3 to precipitate calcium. The chemical reaction is: Mg2++Ca(OH)2→Mg(OH)2↓+Ca2+ Ca2++Na2CO3→CaCO3↓+2Na+
The lime-soda ash method uses Ca(OH)2 (grey milk) to precipitate magnesium and Na2CO3 to precipitate calcium. The chemical reaction is: Mg2++Ca(OH)2---Mg(OH)2+Ca2+ Ca2++Na2CO3---CaCO3+2Na+
1. What is the principle of the lime soda ash method for refining brine? answer: The lime-soda ash method of refining brine uses Ca(OH)2 (grey milk) to precipitate magnesium and Na2CO3 to precipitate calcium. The chemical reaction is Mg2+ +Ca(OH)2→Mg(OH)2↓+Ca2+ Ca2++Na2CO3→CaCO3↓+2Na+
The lime-soda ash method uses Ca(OH)2 (grey milk) to precipitate magnesium and Na2CO3 to precipitate calcium. The chemical reaction is: Mg2++Ca(OH)2→Mg(OH)2↓+Ca2+ Ca2++Na2CO3→CaCO3↓+2Na+
The lime soda ash method for refining brine uses Ca(OH)2 (grey milk) to precipitate magnesium, and sodium carbonate to precipitate Ca2+. The chemical reaction formula is:: Mg2+ + Ca(OH)2 =Mg(OH)2 + Ca2+ Ca2+ +Na2CO3 =CaCO3 +2Na+
The lime soda ash method for refining brine uses Ca(OH)2 to precipitate magnesium and Na2CO3 to precipitate calcium. The chemical reaction is: Mg2++Ca(OH)2→Mg(OH)2↓+ Ca2+ Ca2++Na2CO3→CaCO3↓+ 2Na+
The lime-soda ash method of refining brine uses Ca(OH)2 (grey milk) to precipitate magnesium and Na2CO3 to precipitate calcium. The chemical reaction is: Mg2++Ca(OH)2→Mg(OH)2↓+Ca2+ Ca2++Na2CO3→CaCO3↓+2Na+
The lime-soda ash method uses calcium hydroxide (milk of lime) to precipitate magnesium and sodium carbonate to precipitate calcium. The chemical reaction is: Mg2++Ca(OH)2→Mg(OH)2↓+Ca2+ Ca2++NaCO3→CaCO3↓+2Na+
