- You purchase a bottle of water. On checking its pH, you find that it is not neutral, as you might have expected. Instead, it is slightly acidic. Why?arrow_forwardIdentify the conjugate acid-base pairs in the reaction of H3PO4 with water.arrow_forwardAcidity of a solution is determined by the concentration H of hydrogen ions in the solution (measured in moles per liter of solution). 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.) (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.)arrow_forward

(a) pOH = 8.5 = 4.2 (b) pOH (c) POH = 1.7 (d) pOH = 7.0arrow_forwardCalculate the molar H3O+ion concentration of a solution that has a pH of (A) 4.31 (B) 13.89 (C) 5.32 (D) 4.48arrow_forwardAs the pH of a solution increases (gets higher), what happens to the acidity of the solution?(a) The acidity increases. (b) The acidity decreases.(c) The acidity remains constant.arrow_forward
- The pH of a chemical solution is given by theformula pH = - log10 [H+ ] where [H+ ] is the concentration of hydrogen ions in molesper liter. Values of pH range from 0 (acidic) to 14 (alkaline).(a) What is the pH of a solution for which [H+ ] is 0.1?(b) What is the pH of a solution for which [H+ ] is 0.01?(c) What is the pH of a solution for which [H+ ] is 0.001?(d) What happens to pH as the hydrogen ion concentration decreases?(e) Determine the hydrogen ion concentration of an orange (pH = 3.5).(f) Determine the hydrogen ion concentration of human blood (pH = 7.4).arrow_forward6. Acids and bases are defined by their donation or acceptance of a proton according to the (a) Arrhenius model. (b) Bronsted-Lowry model. (c) Lewis model.arrow_forwardWhat is the basis for referring to the hydrogen ion as a proton? (a) The Arrhenius definition of an acid. (b) The Brønsted-Lowry definition of an acid x (c) The Lewis definition of an acid. (d) H* exists as a bare proton. (e) None of these.arrow_forward
