For each scenario below, select the color of the solution using the indicator thymol blue during the titration. When you first add indicator to your Na2CO3 solution, the solution is basic (pH ~10), and the color is [Select] At the equivalence point for the titration, the moles of added HCI are equal to the moles of Na2CO3. One drop (or less!) past this is called the endpoint. The added HCI begins to titrate the thymol blue indicator itself. At the endpoint, the indicator color is [Select] When you weren't paying attention and added too much HCI (~12 mL extra), the color is [Select] When you really weren't paying attention and reached the second equivalence point of Na2CO3, the color is ✓ [Select] blue yellow red orange green Question 9
I really need help with this review problem thanks
Build a titration curve for the following scenarios. Make sure to label your accesses and anyother appropriate pieces of data. Each curve should have a minimum of 4 data points, but youcan use the following to help structure your curvea) Initial pHb) pH at Veqc) pH=pka (if applicable)d) pH when excess titrant is addede) Additional pH point near Veq for Strong Acid/Strong Base titrations (in order to see thesteepness of the slope) OR additional pH point in buffer zone for titrations with a Weakcompound.
