Great video

[@way2saturn]

0:00 to 4:09 same observation of Zn+2 as aluminium

[@kirarieletoad]

Perfect sir exactly what my teacher explained in class

[@jonerasmus9399]

Best video I've seen on this topic .However, I would have just included zinc, it also forms a white ppt in NaOH ! , its soluble in excess giving colorless solution.

Can you do an experiment for Magnesium ion with titan yellow and NaOH in excess pls😢😢

[@DonathilleNyirabucyangenda]

Thanks for this video ❤❤❤

[@JTSchemenauer]

I was heating melted electronic scraps in hcl. Poured in NaOH(aq) and got a black precipitate. I have no idea what it could be. I thought it was iron but it wasn't green or red. I guess I'm going to have to dry it and do a flame test to find out.

What's the theory behind this experiment

YOU HAVE THE VOICE OF COGNITO

[@prozain4296]

Nah not really

[@aminthedrifter]

Yeah I see the similarities but then there are stark differences too.

[@mannanhanda5564]

Awesome!

[@daniellelee2862]

why does excess sodium hydroxide redissolve the white precipitate in aluminum?

[@ltull713]

Aluminium is amphoteric so is able to act as both an acid and a base, it effective acts as an acid towards the hydroxide, neutralising it (simple explanation).
