or what purpose do we use an indicator? To indicate the endpoint of an acid-base titration To determine its K(In) To measure its color To determine its pK(In) To make a buffer solution Tries 0/3 Tolerance 0 Points Earned 0 Points for 1st Try 5 Points for 2nd Try 3 Points for 3rd Try 1 2. Work Problem What physical property of indicators makes them useful for this purpose? Tries 0/3 Tolerance 0 Points Earned 0 Points for 1st Try 5 Points for 2nd Try 3 Points for 3rd Try 1 3. Work Problem How will the pH solutions of assigned values be prepared in this experiment? Tries 0/3 Tolerance 0 Points Earned 0 Points for 1st Try 5 Points for 2nd Try 3 Points for 3rd Try 1 4. Work Problem What quantity will you determine graphically in this experiment to help achieve the main objective? Tries 0/3 Tolerance 0 Points Earned 0 Points for 1st Try 5 Points for 2nd Try 3 Points for 3rd Try 1 5. Work Problem How willl you assess the quality of the data in this experiment
