How to prevent sodium aluminate from precipitation
Will alkali excess?However, there will be some flocculent sediments at the bottom of the sodium hydroxide solution. I think it may be explained: 1. The solution absorbs the carbon dioxide gas in the air, which may generate aluminum hydroxide 2. Water waterInsufficient purity, containing some heavy metal ions 3. If it is placed in a glassware, it may be with silicon dioxide 4. or the purity of raw materials is not enough.

The molar ratio of sodium and sodium hydroxide is 1.42: 1. Is it wrong? Should it be chosamine and aluminum hydroxide.In addition, the sediment is aluminum hydroxide, because sodium aluminum is too high or too low in aluminum and sodium, which is easily hydrolyzed into aluminum hydroxide
