WebIn chemistry, pH (/ p iː ˈ eɪ tʃ /), also referred to as acidity, historically denotes "potential of hydrogen" (or "power of hydrogen"). It is a scale used to specify the acidity or basicity of an aqueous solution.Acidic solutions (solutions with higher concentrations of H + ions) are measured to have lower pH values than basic or alkaline solutions. WebIn contrast, the molecule of pure natural rubber is thought to contain about 75,000 carbon atoms and about 120,000 hydrogen atoms. So you can see that molecules differ greatly in size. Simple molecules like that of water are only a few billionths of an inch in length. The rubber molecule is thousands of times larger.
