50. Chemists have defined the pH (Hydrogen Potential) of a solution by pH = -log[H+] where [H+] represents the concentration of the hydrogen ion in moles per liter. The pH scale ranges from 0 to 14 depending on a solution’s acidity or alkalinity. Values below 7 indicate progressively greater acidity, while above 7 are progressively more alkaline. Normal, unpolluted rain has pH of about 5.6. Since the pH scale is logarithmic, keep in mind that there is tenfold in hydrogen ion concentration for each pH unit. An environmental concern involves the destructive effects of acid rainfall ever had a pH of 2.7, what is the hydrogen ion concentration?
