Why is aluminium carbonate unstable? - Chemistry Stack Exchange
2018年6月13日 · Aluminium carbonate is a salt of a very weak acid and a weak base, so it tends to hydrolyze. Similar may be said for a much easier available aluminium sulfide: it reacts with water in the air, so it is a common tool for rebellious teenagers if they can get the materials. Moreover, aluminium cation is extremely small.
Does aluminium carbonate exist? - Chemistry Stack Exchange
2017年6月12日 · The reason why aluminium carbonate cannot exist is because it is simply too unstable and would rather be broken down instead. Firstly, the aluminium ion is highly polarising with a high positive charge density (as it is a small ion which is triply charged). Thus, distortion of the carbonate ion's electron cloud is very great.

How to easily distinguish salts physically? Edit
2016年2月4日 · I will be given one of them. I know all the tests I have to undertake to identify these salts (such as ash test, flame test, sodium carbonate extract tests etc). But I would like to know if there is any quick way to easily identify my salt on looking it or some easy tests so that I get a leverage over time and could finish my tests easier.
