Briefly describe the brine refining method.
Briefly describe the brine refining method. Answer: The refining method is to add alkaline substances such as Ca(OH)2 and NaOH to make Mg2+ form Mg(OH)2 precipitate, and add various soluble carbonates such as: Na2CO, (NH4)2CO3, etc., cause Ca2+ to form CaCO3 precipitate, and the generated precipitate can be removed by sedimentation method.
The method of refining is to add alkaline substances such as Ca(OH)2 and NaOH to cause Mg2+ to form Mg(OH)2 precipitate, and add various soluble carbonates such as: Na2CO, (NH4)2CO3, etc., cause Ca2+ to generate CaCO3 precipitate, and the generated precipitate can be removed by sedimentation method.

The refining method is to add NaOH to cause Mg2+ to form Mg(OH)2 precipitate; then add Na2CO3 to cause Ca2+ to form CaCO3 precipitate. The generated precipitate can be removed by sedimentation method.
The refining method is to add alkaline substances such as calcium hydroxide and sodium hydroxide to cause magnesium ions to form magnesium hydroxide precipitates. Add various soluble carbonates such as sodium carbonate to cause calcium ions to form calcium carbonate precipitates. The resulting precipitates can be removed by sedimentation.
The refining method is to add alkaline substances such as calcium hydroxide and sodium hydroxide to cause magnesium ions to form hydroxide precipitates, and add various soluble carbonates such as: Sodium carbonate, ammonia carbonate, etc. cause calcium ions to form calcium carbonate precipitates, and the resulting precipitates can be removed by precipitation.
