Insoluble
|
incapable of being dissolved

Hydroxide ions
|
Consists of an oxygen and a hydrogen atoms held together by a covalent bond, and carrying a negative electric charge
|
|
|
Precipitate
|
solid that comes back out of its solution because of a chemical reaction or physical change.
|
|
|
Antacid
|
Counteracting or neutralizing acidity
|
|
|
OH
|
Hydroxide ion
|
|
|
Solute
|
the substance dissolved in a given solution
|
|
|
Ionic compound
|
chemical compound in which ions are held together in a lattice structure by ionic bonds
|
|
|
Saturated
|
describes a solution that holds the total amount of solute that it can hold under given conditions
|
|
|
Unsaturated
|
having the power to dissolve still more of a substance.
|
|
|
Supersaturated solutions
|
solution that contains more of the dissolved material than could be dissolved by the solvent under normal circumstances

|
|
Substance
|
a material with a definite chemical composition
|
|
|
Molecular compound
|
compound regarded as a union of molecules retaining their identities
|
|
|
Non-polar molecules
|
Molecule which has no separation of charge, so no positive or negative poles are formed
|
|
|
polar molecules
|
mostly positive on one side and mostly negative on the other
|
|
|
PH scale
|
measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is bases
