Term | Definition |
NEUTRAL | A liquid with a pH value equal to pH7. |
ACID | A liquid with a pH value less than pH7. |
ALKALI | A liquid with a pH value greater than pH7. |
ALUMINIUM | A very light metal used to make kitchen foil and saucepans. |
ATOM | The smallest possible part of a element. |
BUNSEN BURNER | A piece of apparatus that burns gas and is used to heat apparatus. |
CHROMATOGRAPHY | A way of separating a mixture of coloured dyes or pigments such as found in ink. |
COMPOUND | The substance formed when two or more elements are chemically combined together. eg HYDROGEN (element) + OXYGEN (element) = WATER |
CONDENSE (condensation) | This is what happens when a gas turns to a liquid due to being cooled down. For example when steam touches a cold mirror. |
COPPER | A pink metallic element. It is a very good conductor of heat and electricity. It is the metal that wires are usually made from. |
DECOMPOSE (decomposition) | The chemical change that takes place when a compound is split apart into two (or more) simpler substances, usually by heating. |
DISTILLATION | The name of the process used for obtaining the SOLVENT from a SOLUTION. Eg obtaining pure water from sea water. |
ELEMENT | Chemical substances that contain only one kind of atom. They are listed in the Periodic Table. |
EVAPORATION | The process for obtaining the solute from a solution by warming the solution and letting the solvent evaporate away. |
FILTRATION | The process used for separating a SOLID from a LIQUID. Eg removing dirt from water |
GRAPHITE | A form of carbon. The black substance inside pencils (the pencil lead). |
IMMISCIBLE | Two liquids that will not mix together (like oil and water) |
INSOLUBLE | When a substance cannot dissolve. |
MALLEABLE | A substance that can be hammered into thin sheets. Includes most metals. Good examples are gold, copper or lead. |
MIXTURE | Something that contains at least two substances that can be separated without a chemical reaction taking place. |
MOLECULE . | The particle formed when two or more atoms chemically join together. |
pH SCALE | A scale of numbers (from 1 to 14)which shows how acidic or alkaline a liquid is. |
REDUCE (reduction) | The kind of reaction happens when we remove the oxygen from a compound. |
RESIDUE | The solid remaining in the filter paper after filtering. |
SOLID | A solid is one of the three states of matter (the other two being liquids and gases). |
SOLUBLE | This is how we describe a substance that can be dissolved. Sugar is soluble in water. |
SOLUTE | The solid that has been dissolved when we make a solution. |
SOLUTION | This is the liquid obtained by dissolving one substance in another. |
STATES OF MATTER | SOLID, LIQUID and GAS are known as this. |
FILTRATE | The liquid left behind after filtering. |
REDUCING AGENT | An element good at removing oxygen from a compound. (Eg magnesium) |
SOLVENT | A liquid good at dissolving things |
OXIDISE | A kind of reaction when oxygen comines with another element. |
