Cation Test: Iron(III) Ions

- เผยแพร่เมื่อ 16 ก.ย. 2024
- Solutions containing iron(III) ions are typically yellow, reddish-brown or orange in colour depending on the concentration of iron(III) ions.
To test for the presence of iron(III) 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 reddish-brown precipitate forms. Upon addition of excess sodium hydroxide, the reddish-brown precipitate remains insoluble.
2) Ammonia Test - To a sample of your solution, add a few drops of ammonia solution. A reddish-brown precipitate forms. Upon addition of excess ammonia solution, the reddish-brown precipitate remains insoluble.
Your videos are helping me effectively memorize these tests for my May/June IGCSE. Thank you so much!
You are the best in testing cations... So simple but effective.... It helped me a lotttt..... Thanksss a lottttt
Wasn't paying attention to the video when it first started and the music made me think it was an ad for mystery tackle box!
Thank you for the video! Helped me out with my AP Chem lab questions.

Oh yeah yeah
I'm sorry
Thank you so much
Sir, I have extracted some small pieces of metallic metal from my backyard soil, is there a way to test the pieces for iron or if it is some other metallic metal?
Aboslute lifesaver mate.
thank you for the helpful video
what is the chemical equation for both of the experiments ?
0:48 that is the first time ive ever seen anyone mix like that
Lollll
Thanks !!!
Thanx a lottt
