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 argued that bases are neutral compounds that either dissociate or ionize in water to give OH-ions and a positive ion. NaOH is an Arrhenius base because it dissociates in water to give the hydroxide (OH -) and sodium (Na +) ions.he fact that water dissociates to form H + and OH-ions in a reversible reaction is the basis for an operational definition of acids and bases that is more powerful than the definitions proposed by Arrhenius.
