Use the following information on pH. Chemists define pH by the formula pH = -log10[H], where [H+] is the hydrogen ion concentration measured in moles per liter. For example, if [H] = 10-5, then pH 5. Solutions with a pH of 7 are said to be neutral; a pH below 7 indicates an acid; and a pH above 7 indicates a base. (A calculator is helpful for this exercise.) (a) For some fruit juices, [H] = 2 x 10-3. Determine the pH. (Round your answer to one decimal place.)) Classify these juices as acid or base. O acid O base (b) For sulfuric acid, [H] 1. Find the pH.
