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 Acid. An Arrhenius acid is a molecule that when dissolved in water will donate an H+ in solution. Simply put, a proton donor. The trick to recognizing an Arrhenius acid is to look for a molecule that starts with an H, and typically contains an oxygen or halogen.n Arrhenius base is a molecule that when dissolved in water will break down to yield an OH-or hydroxide in solution. To recognize the Arrhenius base look for a molecule ending in OH, but not following CHx which refers to an alcohol. Arrhenius base examples include: 1  Sodium hydroxide â NaOH.
