Chemists use the negative of the logarithm of the concentration of hydrogen ions to define the pH scale, as shown in the following formula. pH = -log (H) Lower pH values indicate a more acidic solution. (a) Normal rain has a pH value of 5.6. Rain in the eastern United States often has a pH level of 3.8. How much more acidic is this than normal rain? (Round your answer to two decimal places.) 63.10 times as acidic as normal rain (b) If the pH of water in a lake falls below a value of 5, fish often fail to reproduce. How much more acidic is this than normal water with a pH of 5.6? (Round your answer to two decimal places.) * times as acidic as normal waterarrow_forward
