self ionization of water | the chemical reaction in which a proton is transferred from one water molecule to another, in pure water or an aqueous solution, to create the two ions, hydronium, H3O+ and hydroxide, OH−. |
pH | a measure of the acidity or basicity of an aqueous solution |
pOH | used as a measure of the concentration of hydroxide ions, OH−, or alkalinity. |
acid-base indicators | are substances which change color with pH |
transition interval | range in concentration of a species |
pH meter | an electronic instrument used for measuring the pH of a liquid |
titration | used to determine the unknown concentration of an identified analyte. |
equivalence points | when a titrant is added and is stoichiometrically equal to the amount of moles of substance |
end point | the point at which the indicator changes color in a colorimetric titration |
standard solution | |
primary standard |
