The ammonium cation is a positively-charged polyatomic ion with the chemical formula NH+4 or [NH4]+. It is formed by the protonation of ammonia (NH3). Ammonium is also a general name for positively charged or protonated substituted amines and quaternary ammonium cations ([NR4]+), where one or more hydrogen atoms are replaced by organic groups (indicated by R). (Wikipedia).
A Level Chemistry Revision "Testing for Ammonium Ions"
In this video, we look at how to test for ammonium ions. This is a relatively simple chemical test but it does contain details that you need to learn.

Volcano of Ammonium Dichromate
The classic ammonium dichromate volcano experiment. The experiment is extremely simple: just pour a mound of ammonium dichromate and light it on fire. What's happening is the ammonium is the fuel while the dichromate is the oxidizer and burns the ammonium to nitrogen gas and water.

Acids and Bases - Short Revision || CBSE Science || || Infinity Learn Class 9&10
Acids and bases are two types of substances that are fundamental to chemistry. An acid is a substance that donates protons (hydrogen ions, H+) to a solution, while a base is a substance that accepts protons or donates hydroxide ions (OH-) to a solution. There are several ways to define and

Americium - Periodic Table of Videos
We're at the UK's National Nuclear Laboratory (Sellafield) for a look at some Americium. It is used in smoke detectors but could also be a key power-source for the future of space travel. With thanks to the National Nuclear Laboratory, especially Mark Sarsfield. http://www.nnl.co.uk/ Mor

Nitrate from Ammonia using Air?
We have previously assembled an ozone generator, so we try out an ambitious project that would see the nitrate ion form from the ammonium ion. Will the ozone be magical, or will I melt the circuit board?? Paper reference: Ozonation of ammonia in wastewater https://www.sciencedirect.com/sc

In this video I make hydrobromic acid from sulfuric acid and sodium bromide. You can also use potassium bromide.
