QUESTION 8 The compound ammonia, NH3, is a weak base when dissolved in water. Which of the following is the correct equation for the reaction of ammonia in water? a NH3(aq) + H20(0) NH4(aq) + OH(aq) NH3(aq) + OH(aq) NH2 (aq) + H20(0) NH3(aq) + H20(1) -NH2 (aq) + H30*(aq) NH3(aq) + H200) NH2 (aq) + H30(aq) NH3(aq) + H30aq) NH4+ (aq) + H20(0) QUESTION 9 What is the pH of a solution that is 0.17...
Dissolved ammonia is a common contaminant in drinking water, streams, and rivers. The dissolved form can cause an unpleasant taste in the water and is toxic to many aquatic life forms. Gaseous ammonia (NH3) has an unpleasant odor that has been described as similar to baby diapers or window cleaner. b. Fish are very sensitive to un-ionized ammonia (NH3) and concentrations as low as I .0 mg/L can be toxic. If you took a sample of water downstream of a...

Ammonia, NH3, is a weak base with a Kb value of 1.8×10−5. Part A What is the pH of a 8.50×10−2 M ammonia solution? Part B What is the percent ionization of ammonia at this concentration?
An aqueous solution of ammonia is prepared (ammonia is weak base). How can we achieve the condition where [NH4+] = [NH3]? NH3 (aq) + H2O (l)-----OH– (aq) + NH4+(aq) A) By decreasing the pH. B) By increasing the pH. C) By heating the solution. D) By diluting the solution with water. E) By concentrating the solution.

4. When 0.100 mol ammonia is dissolved in water to make a 500 mL solution, the following equilibrium is established NH3(aq) + H2O(0) - NH. (aq) + OH(aq) K = 1.8 x 10-5 a. Find the concentration of OH' and the pH of the solution at equilibrium. Remember: pOH = -log(OH) and pH + pOH = 14 b. Consider the following reaction: 2H2O(1) 2 H,0*(aq) + OH(aq) K = 1.0 x 10-14 Write the equilibrium expression and find the value...
Strong base is dissolved in 765 mL of 0.400 M weak acid (Ka =
