Chemistry Terms -Glossary
1-Catalyst – a chemical compound used to change the rate (either to speed up or slow down) of a reaction, but is regenerated at the end of the reaction.
2-chemical reaction – the change of one or more substances into another or multiple substances
3-compound – a substance that is made up of two or more chemically bonded elements
4-covalent bond – chemical bond that involves sharing electrons
5-cuvette – glassware used in spectroscopic experiments. It is usually made of plastic, glass or quartz and should be as clean and clear as possible
6-condensation – the phase change from gas to liquid
7-conductor – material that allows electric flow more freely
8-crystal – a solid that is packed with ions, molecules or atoms in an orderly fashion
9-colloid – mixture of evenly dispersed substances, such as many milks
10-combustion – an exothermic reaction between an oxidant and fuel with heat and often light
11-centrifuge – equipment used to separate substances based on density by rotating the tubes around a centred axis
12-cation – positively charged ion
13-cell potential – the force in a galvanic cell that pulls electron through reducing agent to oxidizing agent
14-deposition – settling of particles within a solution or mixture
15-dissolution or solvation – the spread of ions in a monosacharide
16-double bond – sharing of two pairs of electradodes
17-dipole moment – the polarity of a polar covalent bond
18-deliquescence – substances that absorb water from the atmosphere to form liquid solutions
19-deionization – the removal of ions, and in water’s case mineral ions such as sodium, iron and calcium
20-dipole – electric or magnetic separation of charge
