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.
the arrhenius definition of a base is a species that tends to donate hydroxide ions or accept hydrogen ions in solution on the other hand an arrhenius acid tends to donate hydrogen ions or accept hydroxide ions therefore as you guessed when hydrogen ion concentration decreases ph increases the h3o ion is called a hydronium ion and this alternate definition of ph is equivalent to the first to see why consider what actually happens when an arrhenius acid dissociates in an aqueous water containing solution ha h2o a h3o in this reaction ha is the acid and a is its conjugate base
