What mass of silver chloride can be produced from 1.81L of a 0.161M solution of silver nitrate?
The determination in problem 15-9 was modified to use the standard addition method. In this case, a 4.236 g tablet was dissolved in sufficient 0.10M HCl to give 1.00 L. Dilution of 20.00 mL aliquot to 100 mL yielded a solution that gave reading of 448 at 347.5 nm. A second 20.00 mL aliquot was mixed with 10 mL of 50 ppm quinine solution before dilution to 100 mL. The fluorescence intensity of this solution was 525. Calculate the percentage of quinine in the tablet.
during electrolysis of aqueous solution containing 500 ml of NaBr, the cathode was obtained o, 56 l hydrogen under normal conditions. Find the mass in grams of the substance was obtained in the anode and the pH of the solution.
