Glossary

Acidic Solution:

are any solution that has a higher concentration of hydrogen ions than water

Arrhenius Acid:
is a substance that when dissolved in water increases the concentration of hydrogen ion, H⁺

Arrhenius Base:
is a substance that when added to water increases the concentration of hydroxide ion, OH^-

Basic Solution:
A solution that has a higher concentration of hydroxide ions that hydrogen ions; a pH between 7 and 14.

Bronsted Acid:
is defined as any substance that can donate a hydrogen ion (proton)

Bronsted Base:
 is any substance that can accept a hydrogen ion (proton).

Conjugate Acid:
is the acid member, HX, of a pair of compounds that differ from each other by gain or loss of a proton. A conjugate acid can release or donate a proton.

Conjugate Base:
is the base member, X-, of a pair of compounds that transform into each other by gaining or losing a proton. The conjugate base gains or absorbs a proton in a chemical reaction.

End point:
The point at which an indicator changes colour and a titration is stopped

Indicator:
Any of various substances, such as litmus or phenolphthalein, that indicate the presence, absence, or concentration of another substance or the degree of reaction between two or more substances by means of a characteristic change, especially in color.

pH:
is a measure of  hydrogen ion concentration

pOH:
Measures the base of a solution. It is the negative log of the concentration of the hydroxide ions

Titration:
is the process in which one solution is added to another solution such that it reacts under conditions in which the added volume may be accurately measured.
