Basic Chem

a solution in which water is the solvent

the smallest representative particle of an element

A substance that is able to donate a H+ ion ( a proton) and hence increases the concentration of H+ when it dissolves in water

Capable of behaving as an acid or a base

A substance that is an H+ acceptor. A base produces and excess of -OH when it dissolves in water

A substance that cannot be separated into simpler substances by chemical means

process in which one or more substances are converted into other substances, also called chemical reactions

A substance composed of two or more elements united chemically in definite proportions

A notation that uses atomic symbols with numerical subscripts to convey the relative proportions of atoms of the different elements in a substance

Properties that describe a substance's composition and its reactivity; how the substance reacts, or changes into other substances

the quality of solute present in a given quantity of solvent or solution

The process of preparing a less concentrated solution from a more concentrated one by adding solvent

A negatively charged subatomic particle found outside the atomic nucleus; it is part of all atoms

An atom or group of atoms that imparts characteristic chemical properties to an organic compound

water-attracting

water-repelling

Anything that occupies space

A measure of the amount of material in an object. It measures the resistance of an object being moved

Liquid that mix in all proportions

a combination of two or more substances in which each substance retains its own chemical identity

A chemical formula that indicates the actual number of atoms of each element in one molecule of a substance

The mass of the collection of atoms represented by the chemical formula for a molecule

A chemical combination of two or more atoms

An insoluble substance that forms in, and separates from, a solution

the determination of the presence or absence off a particular substance in a mixture

The determination of the amount of a given substance that is present in the sample

an ionic compound formed by replacing one or more H+ of an acid or by other cations

The amount of a substance that dissolves in a given quantity of solvent at a given temperature to form a saturated solution

A substance dissolved in a solvent to form a solution. It is normally the component of a solution present in the smaller amount

The dissolving medium of a solution. It is normally the component of a solution present in the greater amount

A mixture of substances that has a known uniform composition; a homogeneous mixture

Tending to evaporate readily
