Electrolysis has many commercial uses, for example: extracting reactive metals such as aluminium from their ores or compounds anodising...

Yes, it's exactly what everybody wanted- a relationship between mole concept and electrolysis. As we discussed in the previous post, ions...

According to the CSEC syllabus, you should be able to discuss the electrolysis of certain substances, especially in how electrolysis...

If a molten electrolyte is electrolysed, there is no competition for discharge at the electrodes since there is only one type of cation...

When electrolytes conduct electricity, they are decomposed by the current. This is called electrolysis.

Electrochemistry deals with the relationship between electricity and chemical phenomena. So, if you think about it, elctrochemistry is...

Oxidizing agents cause another substance to be oxidized. The oxidizing agent accepts electrons, meaning the oxidizing agent itself is...

As we discussed in this previous post, redox reactions are reactions where reduction and oxidation occur simultaneously.

While studying chemistry, you will come across several types reactions, and it is often necessary to predict the products of a reaction...

So, we all know by now that there are tiny bonds holding all of the substances around us together, on the atomic and molecular level.

The method used to prepare a certain salt is dependent on the solubility of the salt in water. So, it is necessary that you first know...

A salt is a substance formed when metal ions or the ammonium ion take the place of the hydrogen ion(s) of an acid.

A base is a proton acceptor. As was discussed in this previous post on acids, a proton is an H⁺ ion. Many bases are metal oxides/hydroxides

An acid is a substance that donates hydrogen ions, meaning it is a hydrogen donor. When dissolved in water, acids liberate hydrogen ions.

The limiting reagent is the reactant which produces the smallest yield of products. In the first case, oxygen is the limiting reagent...

In a balanced and complete equation, you are given a lot of information. Apart from what the products are and what the reactants are...

You may already be familiar with the description of a solution as dilute, concentrated or saturated. However, with the mole, we have a...

Gases When dealing with gases, due to their low density, we measure them by volume instead of mass. CSEC requires that you know...

Relative Atomic Mass of Elements Before we get to talking about moles, we need to cover relative masses. The relative atomic mass of an...
