Complete the equationfor the neutralization reaction that occurs during the titration. 30. Determine the concentration of the HCl(aq) solution, using the titration data. 31. Base your answer to the following question on the information below. In a titration, 20.0 milliliters of 0.15 M HCl(aq) is exactly neutralized by 18.0 milliliters of KOH(aq). Compare the number of moles of H + (aq) ions to the number of moles of OH (aq) ions in the titration mixture when the HCl(aq) is exactly neutralized by the KOH(aq). Base your answers to questions 32 through 34 on the information below. Some carbonated beverages are made by forcing carbon dioxide gas into a beverage solution. When a bottle of one kind of carbonated beverage is first opened, the beverage has a ph value of After the beverage bottle is left open for several hours, the hydronium ion concentration in the beverage solution decreases to of the original concentration. Determine the new ph of the beverage solution. 33. Using Table M, identify one indicator that is yellow in a solution that has the same ph value as this beverage. 34. State, in terms of the ph scale, why this beverage is classified as acidic.
4 Base your answers to questions 35 through 37 on the information below. In liquid water, an equilibrium exists between H2O( ) molecules, H + (aq) ions, and OH - (aq) ions. A person experiencing acid indigestion after drinking tomato juice can ingest milk of magnesia to reduce the acidity of the stomach contents. Tomato juice has a ph value of 4. Milk of magnesia, a mixture of magnesium hydroxide and water, has a ph value of What is the color of thymol blue indicator when placed in a sample of milk of magnesia? 36.

Base your answers to questions 38 through 40 on the information below. Soil ph can affect the development of plants. For example, a hydrangea plant produces blue flowers when grown in acidic soil but pink flowers when grown in basic soil. Evergreen plants can show a yellowing of foliage, called chlorosis, when grown in soil that is too basic. Acidic soil can be neutralized by treating it with calcium hydroxide, Ca(OH)2, commonly called slaked lime. Slaked lime is slightly soluble in water. 38. Write an equation, using symbols or words, for the neutralization of the ions in acidic soil by the ions released by slaked lime in water. 39. An evergreen plant has yellowing foliage. The soil surrounding the plant is tested with methyl orange and bromthymol blue. Both indicators turn yellow in the soil tests. State, in terms of ph value, why the yellowing of the plant is not due to chlorosis. 40. Compare the hydrogen ion concentration to the hydroxide ion concentration in soil when a hydrangea plant produces pink flowers.

The beverage is acidic because its ph value is below 7. A ph of 3 is in the acid range on the ph scale. 35. blue 36. OH (aq) or OH or hydroxide ion 37. The H + ion concentration in tomato juice is 10 6 times greater. The hydrogen ion concentration in tomato juice is greater than that in milk of magnesia. Milk of magnesia has a lower concentration of H3O + ions. 38. Examples: H3O + (aq) + OH - (aq) 2H2O( ) ; H + + OH - HOH hydrogen ions + hydroxide ions water; hydroxide ions + hydronium ions water 39. Examples: The ph is between 4.4 and 6.0, which indicates an acidic soil. The ph of the soil surrounding the plant is below 6.0. For chlorosis, the soil ph must be above Examples: The hydroxide ion concentration is greater than the hydrogen ion concentration. The H3O + concentration is less than the OH - concentration. [OH - ] > [H3O + ]
