General chemistry

All molecules in an "ideal solution" interact in exactly the same way; the solvent-solvent, solvent-solute, and solute-solute intermolecular forces are all equivalent. Ideal solutions obey Raoult's ...

Pyrophoric

Chemistry; General chemistry

Catches fire spontaneously when exposed to air at normal room temperature. For example, powdered potassium metal is pyrophoric.

Calorimeter

Chemistry; General chemistry

An insulated vessel for measuring the amount of heat absorbed or released by a chemical or physical change.

Hydroxyl

Chemistry; General chemistry

1. An -OH group within a molecule. 2. A free radical formed by abstraction of a hydrogen atom from water.

Precision

Chemistry; General chemistry

Precision is reproducibility. Saying "These measurements are precise" is the same as saying, "The same measurement was repeated several times, and the measurements were all very close to one ...

Alkoxide

Chemistry; General chemistry

An ionic compound formed by removal of hydrogen ions from the hydroxyl group in an alcohol using reactive metals, e.g. sodium. For example, potassium metal reacts with methanol (CH3OH) to produce ...

Enantiomer

Chemistry; General chemistry

Two molecules that are nonsuperimposable mirror images of each other. One enantiomer rotates plane-polarized light to the left; the other rotates it to the right.
