Acidity 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. pH = − log H
Solution A has a pH value of 5.6 and solution B has a pH value of 2.7. Compare the acidity of the two solutions.
a) Solution A is more acidic by a factor of 2.07b) Solution B is more acidic by a factor of 794.33c) Solution A is more acidic by a factor of 794.33d) Solution A is more acidic by a factor of 2.90
In the year 1980, countries near the United States experienced an increase in acid precipi-
tation. During this same year, the United States had an increase in the burning of fossil fu-
els to power homes and vehicles.
Which statement best describes how these two occurrences are related?
The United States' emissions of sulfur dioxide and nitrogen dioxide increased as a result
of a decrease in the burning of fossil fuels to power homes and vehicles, and wind pat-
terns caused these emissions to travel, leading to the formation of acid precipitation in
other areas.

- Which of the following given statements is NOT true? 1. Oxygen from the air does not dissolve in large bodies of water. Lajos Winkler developed the Winkler Titration Method to determine the amount of dissolved oxygen in water. The purpose of the sulfuric acid in the experiment on determining the dissolved oxygen in a water sample is to make the sample acidic. 2. Deeper levels of water often do not reach 100% air saturation equilibrium because they are not shallow enough to be affected by the waves and photosynthesis at the surface. The dissolved oxygen content is an important index when considering its suitability for town supply. An acidic solution will have a pH greater than 7. Which of the following given statements is true? 3. During and after the collection of the sample of water to be used in the DO determination, it is advisable for the flask with water to contain bubbles. In DO determination, 100% air saturation means that the water is holding more dissolved gas molecules…arrow_forwardConsider two solutions; one of a weak acid and one of a strong acid. How is it possible that a solution of weak acid can have a lower pH than a solution of strong acid? Select one: The concentration of the strong acid is higher than the concentration of the weak acid. The concentration of the weak acid is greater than the concentration of the strong acid. The weak acid only partially dissociates in solution. The strong acid completely dissociates in solution.arrow_forwardEach of the four flasks below contains the same volume of .10 M aqueous acid.

All four solutions will require the same amount of base because they all contain acid of the same concentration B. The solution of pH=1.1 will require the most base since it is the strongest acid and has the highest concentration of H+ C. Neither (A) nor (B) is correct.arrow_forward
