Indicators

For acid-base titrations, organic compounds that exhibit different colors in solutions of different acidities, used to determine the point at which reaction between two solutes is complete.

Dipole-dipole Interactions

Attractive interactions between polar molecules, that is, between molecules with permanent dipoles.

Any of six colorless, crystalline, isomeric acids having the formula C9H10O2, derived from xylene.

Saturated Solution

Solution in which no more solute will dissolve.

Phenol

Hydrocarbon derivative containing an [OH] group bound to an aromatic raing.

 

Hydrogen Bond

A fairly strong dipole-dipole interaction (but still considerably weaker than the covalent or ionic bonds) between molecules containing hydrogen directly bonded to a small, highly electronegative atom, such as N, O, or F.

Primary Voltaic Cells

Voltaic cells that cannot be recharged, no further chemical reaction is possible once the reactants are consumed.
