Intro Biochemistry/Ecology
... A water molecule is polar, because there is an uneven distribution of electrons between the oxygen and hydrogen atoms. Acidic solutions contain higher concentrations of H+ ions than pure water and have pH values below 7. Basic, or alkaline, solutions contain lower concentrations of H+ ions than pure ...
