Refers to acidity or alkalinity of water or soil. An ion is a charged atom or group of atoms in solution or in a gas. Solutions contain equivalent numbers of positive and negative ions.
A single proton with a charge of +1. The dissociation of a water molecule (H O) leads to the generation of a hydroxide ion (OHâ€“) and a hydrogen ion (H+). hydrophilic( hy-droh- fil-ik) [L. hydro, water + Gk. philios, friendly] Having an affinity for water.
see hydronium ion
The positively charged ion in an acid.
The positively charged nucleus of a hydrogen atom. Increasing levels of the hydrogen Ion in the water will cause pH to be lowered.
a positively charged atom of hydrogen; that is to say, a normal hydrogen atomic nucleus
The ion which is left when the hydrogen atom loses its electron, forming a proton. In water the hydrogen ion binds to the water molecules, producing H3O+. Compound which exhibit hydrogen bonding include water and amines.
positive form of a hydrogen atom.
The positively charged nucleus of hydrogen atom. The relative degree of acid or base of a solution (called pH) is a measure of hydrogen ions.
Positively charged hydrogen atom measured as pH to determine degree of acid or base of a solution.
A positively charged species of chemical, symbol H+, the ionized form of the hydrogen atom. The hydrogen ion is hydrated in aqueous solutions and is usually written as H3O+. Neutral water ( pH 7) contains hydrogen ions at a concentration of 10âˆ’7 mol Lâˆ’1. Dissolution of acids in water leads to an increase in the hydrogen ion concentration, and thus a decrease in the PH.
The hydrogen ion is recommended by IUPAC as a general name for all ions of hydrogen and its isotopesCompendium of Chemical Terminology, 2nd edition McNaught, A.D. and Wilkinson, A. Blackwell Science, 1997 [ISBN 0-86542-684-8], also http://www.iupac.org/publications/compendium/index.html online .
