Question
Watch the animation and observe the titration process of a standard 0.100 M sodium hydroxide solution with 50.0 mL of a 0.100 M hydrochloric acid solution. Identify which of the following statements regarding acid-base titration are correct. The pH of the solution changes very slowly at the equivalence point. The pH of the solution at the equivalence point is 7. Before any base is added to the solution, the pH of the solution is 10. At the end point, the pH of the solution is 10 and the color of the solution is pink. The chemical reaction involved in an acid-base titration is a neutralization reaction. At the beginning of the titration process, the pH of the solution increases rapidly.Explanation / Answer
The correct statements are
a) The pH of the solution at the equivalence point is 7.
b) At the end point, the pH of the solution is 10 and the color of the solution is pink
c) The chemical reaction involved in an acid-base titration is a neutralization reaction.
Explanation:
a) the pH of solution changes rapidly at the equivalence point
b) the pH of solution before adding any base is less than 7 .(here it is 1)
c) at the begining of titration the pH of solution changes very slowly
