硝酸镁与碳酸氢钠的反应探究

Study on the Reaction of Magnesium Nitrate with Sodium Bicarbonate

探究硝酸镁与碳酸氢钠是否会生成碳酸镁沉淀。不同浓度的硝酸镁与碳酸氢钠反应,静置后均生成白色沉淀,通过实验证明白色沉淀为三水碳酸镁,说明新相难成导致生成碳酸镁沉淀需要一定时间。

Explore whether magnesium nitrate and sodium bicarbonate will produce magnesium carbonate precipitate. Different concentrations of magnesium nitrate and sodium bicarbonate were put together, produce white precipitate after keeping static. Experiments show that the white precipitate is magnesium carbonatetrihydrate, which is difficult to formation as a new phase.
