A mixture containing only KCl and NaBr is analyzed by the Mohr method. A 0.3172-g sample is dissolved in 50 mL of water and titrated to the Ag,CrO4 end point, requiring 36.85 mL of 0.1120 M AgNO3. A blank titration requires 0.71 mL of titrant to reach the same end point. Report the %w/w KCl and NaBr in the sample.
A chloride unknown weighing 0.3221 g is dissolved in an acidic solution and is treated with silver nitrate. The silver chloride precipitate that forms is filtered, dried, and weighed. The weight of silver chloride obtained is 0.7332 g. Calculate the percentage of Cl- in the unknown chloride sample. Please show working clearly
Which is the correct order of steps in the preparation of a hydrochoric acid standard solution with sodium bicarbonate standard solution. I. Dissolved sodium carbonate (13.25 g) in about 150 mL of distilled water in a beaker II. Solution of sodium carbonate was transferred into a volumetric flask and diluted to mark before mixing. III. Weigh the appropriate amount of the primary standard. IV. Titrate with enough volume of the acid to completely neutralize the base. V. Transfer 10.00 ml primary standard into an erlenmeyer flask and add indicator III, I, II, V, IV III, II, I, V, IV V, III, I, II, IV V, IV, III, I, II

You are planning to determine the concentration of acid in vinegar by titration with a suitable base. The container of vinegar states that the acetic acid concentration in the vinegar is 10%.Suggest a suitable titration to carry out this determination (note all reagents) and estimate the amount of 0.01 mol/l alkali solution that you will require for your class group (assuming 3 titrations by 10 students). Indicate the alkali solution that you will use.
In this activity, you will develop an experimental procedure to solve a problem. Consider the followingscenario:You are the manager of a chemical stockroom, and find a bottle containing approximately one liter of aclear and colorless solution of unknown identity and concentration. Your only clue to its identity is thatit was found between bottles of silver fluoride and sodium fluoride, so it is likely an aqueous solution ofone of those two compounds. You will need to develop a procedure to determine the following:a) The identity of the unknown solutionb) The concentration of the unknown solutionWrite out a precise procedure, which includes all glassware, reagents, and steps. You will also need towrite the calculations that you would need to determine the concentration of the solution. Assume thatyou have access to any reagent you might need
