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

Thanks really helped me with my chemistry lab report

[@aditikumari207]

Amazing background music . . .love the flute ☺️

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.

Really good work. So neatly done. Perfect!

[@hailayt9824]

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

[@DevanshRathore-zx7wo]

U didn't show k4feCN6 test

[@petevenuti7355]

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

[@kirstensee6459]

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

You literally beat the crap out of that test tube

[@हमारीरसोईहमारीपरम्परा]

Ur videos are just osm... Helps a lot

[@m.rurimerangsa5225]

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

[@suhyunkim1463]

nice content, nice music!

[@aswathybiju5916]

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

[@hasanmahmud1351]

Very clear experiment!

[@sanjayagrawal1443]

Nice music

[@petevenuti7355]

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

[@suhyunkim1463]

What is the music you used here?

[@sanjayagrawal1443]

Can u plz do the experment of ZnSO4 +H2S

[@ruwanfernandoyamahaguitarc8443]

Thats actually nice music

[@cancelledcancelled]

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

[@aswathybiju5916]

Rubbish-could also be AL3+

Don't add such background music
