Cation Test: Zinc Ions

Solutions containing zinc ions are typically colourless in colour.
To test for the presence of zinc ions in solution, you may use either the sodium hydroxide test or the ammonia test.
1) Sodium Hydroxide Test - To a sample of your solution, add a few drops of sodium hydroxide solution. A white precipitate forms. Upon addition of excess sodium hydroxide, the white precipitate dissolves.
2) Ammonia Test - To a sample of your solution, add a few drops of ammonia solution. A white precipitate forms. Upon addition of excess ammonia solution, the white precipitate dissolves.

Soothing background music

Here's the equation: Aqueous Sodium Hydroxide Test (NaOH): ZnCl2 + 2NaOH -> Zn(OH)2 + 2NaCl (where Zn(OH)2 is the white ppt in few NaOH and dissolves in excess NaOH) Aqueous Ammonia (in water) Test (NH3*H2O or NH3 + H20): ZnCl2 + 2(NH3*H20) -> Zn(OH)2 + 2NH4Cl (where Zn(OH)2 is the white ppt in few NH3*H20 and dissolves in excess NH3*H20) Hope this helps you. Sorry for the inconvenience about the subscripts but I hope it's still readable.

Thanks really helped me with my chemistry lab report

[@aditikumari207]

Amazing background music . . .love the flute ☺️

[@kirstensee6459]

Thanks for the video! Helped me understand better what's going on without having to do the experiment myself

very nice sir. compared to other channels, you have shown the experiment very clearly. well done. kudos...

[@raheemkhan2007]

You literally beat the crap out of that test tube

[@DevanshRathore-zx7wo]

U didn't show k4feCN6 test

[@petevenuti7355]

What's that do? And what would cause a false positive?

[@zovendas1721]

Really good work. So neatly done. Perfect!

[@m.rurimerangsa5225]

Thank you so much .....The video was of great help to me for my chemistry practical 🤗

[@user-nx5xl3qz6r]

Ur videos are just osm... Helps a lot

[@aswathybiju5916]

Oh thanks I got good marks in chemistry practicals .... Thanks bro .....

[@hasanmahmud1351]

Very clear experiment!

[@suhyunkim1463]

nice content, nice music!

[@sanjayagrawal1443]

Nice music

[@petevenuti7355]

What can cause a false positive and how do you distinguish such cases? Al+3?

[@sanjayagrawal1443]

Can u plz do the experment of ZnSO4 +H2S

[@ruwanfernandoyamahaguitarc8443]

Thats actually nice music

[@suhyunkim1463]

What is the music you used here?

Can the colourless solution be filtered with just 1 piece of filtered paper?

[@aswathybiju5916]

you see this

[@andrewsweeney1869]

Rubbish-could also be AL3+

[@seemamahajan6611]

Don't add such background music
