I'm from Sunderland (a Mackem) and teach A level Chemistry (OCR A specification). Use these videos to help your understanding and get the best possible grade. They have worked for thousands of students before, no matter which exam board they studied, let them work for YOU.

I have organised the channel by a series of playlists. You can find the links to all of my playlists via the link below.

You can also find me on Twitter, Instagram and TikTok (links below)

Feel free to get in touch and let me know what you think. I'm especially keen to hear your suggestions for future channel content. You can even buy me a coffee if you really want to!

Hi. Thanks for sharing this video. What is title of the video “checking for NH4” when what you described was testing for NH3? Or what am I missing in my thinking process?
@orangecaprinun
@orangecaprinun 23 часа назад
how would nh3 get there if it wasnt for nh4 being in the reaction in the first place, but in any case, by applying this test we will learn whether both of them existed or not in the reaction, you can use it for the sake of either one, but the name is usually named after the initial ION, just like in the tests for alkali and alkaline metal ions, transition metal ions, halides, sulfate, carbonate
