Cations

Ammonium

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).

Making Ammonium Formate

In this video we are making ammonium formate, an ammonium salt of formic acid. We will use it to make something called formamide which is even more useful. Patreon: https://www.patreon.com/thyzoid Discord: https://discord.gg/UrjAt44HWH (Let me know if the discord link does not work) Insta

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

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
