A student carried out a non-aqueous titration at chemistry laboratory using 0.1N solution of HCIO4 acid. She obtained with 0.06 N as the calculated normality of HCIO4 acid after the standardization. Standardized HCIO4 acid was titrated with 0.2 g of Ephedrine hydrochloride in mercuric acetate solution. Calculate the percentage of Ephedrine hydrochloride. Volume of titrant consumed at end point was 25 mL. Note: 1 ml of 0.1 M HCIO4 acid is equivalent to 0.02017 g of Ephedrine hydrochloride.

In order to determine the Ka of a weak, monoprotic acid, a student measured the pH of a solution of this weak, monoprotic acid to be 3.617. Based on the full- neutralization titration portion of the experiment, it was found that the total molar concentration of this acid solution was 2.632 M. Using these measurements, what would be the Ka for this weak, monoprotic acid? Ka X 10-7 Please enter as your answer only the underlined numerical part of the Ka above.

All of the acids start out at 0.1 M concentration and 25.0 mL volume. Choose all of the correct statements about these titration curves from the cholces below. The titration curve labelled "D" is generated by the strongest acid in the series. In the curves shown above the stronger the acid the less NaOH required for neutralization. The stronger the acid the more important is the pKa of the Indicator used for titration. The Ka of the acid which generates curve "C" is about 103 The weaker the acid the lower the pH of the neutralization point. The acid which generates curve "D" has the highest neutralization-point pH in the series.

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
