2. If lime juice has a pH of 1.7, what is the concentration of hydrogen ions (in mol/L)
in lime juice, to the nearest hundredth?
The acidity or alkalinity of a solution is defined by
pH = –log[H+] where [H+] is the hydrogen ion concentration, measured in moles per liter.
Solutions with a pH value of less than 7 are acidic; solutions with a pH value of greater than 7 are basic and solutions with a pH of 7 (such as pure water) are neutral.
a) Suppose that you test apple juice and find that the hydrogen ion concentration is [H+] = 0.0003. Find the pH value and determine whether the juice is basic or acidic.
