Acids (Arrhenius)
substances that increases hydrogen (H+) ions when added to water; form hydronium ions (H3O+) when combined in water
Bases (Arrhenius)
substances that produce hydroxide ions (OH-) when added to water
Acids (Bronsted- Lowry)
proton (hydrogen ion) donor
Bases (Bronsted- Lowry)
proton (hydrogen ion) acceptor
Standardization
is the process of determining the exact concentration (normality or molarity) of a solution. Titration is one type of analytical procedure often used in standardization
Acidimetric Analysis
The direct and residual titrimetric analysis of bases using an accurately measured volume of acid.
Alkalimetric Analysis
Analyzing the concentration of acids using a known concentration of an alkaline solution.
