- What is a primary standard? You have weighed out precisely 2.471 g of oxalic acid dihydrate, and diluted it to 250,0 mL. What is its molarity? (Hint: Example 12.1) What is a secondary standard? You have diluted 9 mL of roughly 6 M NaOH to 500 mL. What is the approximate molarity of the base? (Pay attention to significant figures) (Hint: Example 12.2) What is the name of the indicator you are to use and what color does it...

You have been given the task to analyze a large number of samples that contain an unknown concentration of the diprotic acid, hydroselenic acid. You know the concentration is approximately 0.05 to 0.10 M H,Se. However, you do not want to complete a myriad of pH titrations, so you decide to identify some of the expected pH. alues you will encounter. In order to do so. vou have prepared 50.00 mL of 0.105 M H, Se solution as your test...

QUESTION 4 4 points (Extra Credit) Save Answer Bonus question: Kemmi Major is working on a professor's research project. She uses a back-titration technique to determine if her reaction has formed the maximum amount of product. Back-titration works by reacting the species of interest (S) with an excess of the first chemical (A), resulting in complete reaction of the species of interest and some left-over first chemical. Then a second chemical (B) is titrated into the mixture to react with...
