Question 3 (5 points) Match the term to the appropriate definition or example. There is only one term per definition. Dissociates completely in solution 1. Neutralization Glass tube used to measure the volume of the standard solution/titrant being added during a titration 2. Equivalence point 3. End point A double displacement 4. Burette reaction in which water and an ionic compound are produced 5. Strong base When the indicator 6. Erlenmeyer flask changes colour 7. Weak base When the moles of acid are equal to the moles of base

Question 4 (1 point) The following graph is a titration curve that shows the pH at various points in a titration between a weak base and a strong acid. Using the graph and the table of indicators, which of the following indicators would you use in this titration? pH 14 Rapid fall of pH to start with, but the rate of fall slows down. equivalence point 0 25 volume of add added (cm³) Bromothymol Blue, end point range 6.0 - 7.6 Phenolphthalein, end point range 8.0 - 9.0 Bromocresol Green, end point range 4.0-5.6 Phenol Red, end point range 6.8 - 8.2
