Chemistry Vocabulary

5. An uncharged subatomic particle found in the nucleus of an atom.
6. A large molecule made up of repeating units called monomers.
8. A method of volumetric analysis in which a solution of known concentration is added to a solution of unknown concentration until the reaction is complete.
10. The positive electrode. It is positively charged because electrons are drawn away from it.
11. Negative ions; these are attracted to the anode.
13. The amount of a solute that can dissolve in a solvent at a given temperature.
14. A substance which neutralises an acid, producing a salt and water as the only products. A base is a hydrogen ion (H⁺) acceptor.
16. The central part of an atom, containing protons and neutrons.

1. The gain of oxygen or the loss of electrons in a chemical reaction.
2. The substance that is dissolved in a solvent to form a solution.
3. A simple molecule that can be polymerized to form a polymer.
4. A positively charged subatomic particle found in the nucleus of an atom.
7. The amount of substance that contains as many particles (atoms, ions, or molecules) as there are in 12 grams of carbon-12.
9. Organic compounds containing the –OH group. They have the general formula CnH2n+1OH. Ethanol is by far the most important of the alcohols and is often just called ‘alcohol’.
10. A soluble base which produces OH⁻(aq) ions in water.
11. The smallest part of an element that can exist as a stable entity. It has a central nucleus containing neutrons and protons surrounded by electrons in shells. 1 mole of atoms has a mass equal to the relative atomic mass (Ar) in grams.
12. The substance that dissolves the solute to form a solution.
15. A substance which dissolves in water, producing H⁺(aq) ions as the only positive ions. An acid is a hydrogen ion (H⁺) donor.
