acid
have a low pH (1-6) – the lower the number the stronger the acid react with bases to form neutral compounds are corrosive when they are strong are an irritant when they are weak.

Metal hydroxides
Metal hydroxides, such as sodium hydroxide, usually dissolve in water to form clear, colourless solutions. When an acid reacts with a metal hydroxide, the only products formed are a salt plus water.

Metal oxides
Some metal oxides, such as sodium oxide, dissolve in water to form clear, colourless solutions. Many of them are not soluble in water, but they will react with acids. Copper(II) oxide is like this. When an acid reacts with a metal oxide, the only pro

Metal carbonates
Although sodium carbonate can dissolve in water, most metal carbonates are not soluble. Calcium carbonate (chalk, limestone and marble) is like this. When an acid reacts with a metal carbonate, the products formed are a salt plus water,CO2 also forms

How to name salts
The first part of the name comes from the metal in the metal oxide, hydroxide or carbonate.The second part of the name comes from the acid used to make it.

Electrolysis
Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric current is passed through them.
6 of 13
Electrolytes
To be an electrolyte, a substance must be able to conduct electricity. To test for conductivity, include a sample of the substance in a circuit that contains a source of direct current and a bulb or ammeter.If a current flows then its an electrolyte.

charged particles
Particles, usually ions or electrons, that carry electrical charges.
8 of 13
covalent
A covalent substance is a molecule containing one or more covalent bonds (shared pairs of electrons).
9 of 13
electrode
conductor used to establish electrical contact with a circuit.
10 of 13
molecule
A collection of two or more atoms held together by chemical bonds.
