Hydration Calculator. Follow 3 easy steps to see whether you are drinking enough water. The calculator will work out your hydration level based on the information you give about yourself and your daily drinking habits. ( See the methodology.
Arrhenius Acids and Bases. The Arrhenius definition of acids and bases is one of the oldest. An Arrhenius acid is a substance that when added to water increases the concentration of H1+ ions present.The chemical formulas of Arrhenius acids are written with the acidic hydrogens first.An Arrhenius base is a substance that when added to water increases the concentration of OH1- ions present.HCl is an example of an Arrhenius acid and NaOH is an example of an Arrhenius base.he chemical formulas of Arrhenius acids are written with the acidic hydrogens first. An Arrhenius base is a substance that when added to water increases the concentration of OH1- ions present.
Arrhenius bases include ionic compounds that contain the OH-ion, such as NaOH, KOH, and Ca(OH) 2. This theory explains why acids have similar properties: The characteristic properties of acids result from the presence of the H + ion generated when an acid dissolves in water.
