Does anyone else have the problem that when you click on the sodium sulfide bottle, it gives you sodium hydroxide? I put Mg2+ in my test tube, click on Na2S and I get a Mg(OH)2 preciptiate.
I checked with the lab creator and this was his response: “Most metal sulfides are black with a few exceptions. Na2S when dissolved in solution is very basic. Mg does not form a sulfide but it is basic enough for the Mg to form the hydroxide ppt.”
