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.
According to Svante Arrhenius acids are compounds which, when dissolved in water produce hydrogen ions (H +), bases are compounds which, when dissolved in water produce hydroxide ions (OH -).The strength of an acid or a base is the relative number of hydroxide and hydrogen ions measured by the pH scale.Thus, the pH is âthe negative of the common logarithm of the hydronium ion concentration of a solutionâ [(6), p.485].Acids described by Arrhenius are ionizable hydrogen atoms which when combined with water form a hydronium ion (H 3 O +). In aqueous solutions all hydrogen ions are hydronium ions.hus, the pH is âthe negative of the common logarithm of the hydronium ion concentration of a solutionâ [(6), p.485].
