The amount of i−3(aq) in a solution can be determined by titration with a solution containing a known concentration of s2o2−3(aq) (thiosulfate ion). the determination is based on the net ionic equation 2s2o2−3(aq)+i3(aq)⟶s4o2−6(aq)+3i−(a q) given that it requires 29.6 ml of 0.260 m na2s2o3(aq) to titrate a 30.0 ml sample of i−3(aq), calculate the molarity of i−3(aq) in the solution.

Working with si (metric) units for each of the following commonly used measurements, indicate its symbol. liter gram milliliter kilogram meter centigram milligram centimeter kilometer second millimeter milliseconds

You mix the pks of succinic acid are 4.21 and 5.64. how many gramsa graduate student at sdsu wants to measure the activity of a particular enzyme at ph 4.0. to buffer her reaction, she will use a buffer system based on one of the acids listed below, which acid is most appropriate for the experiment? of monosodium succinate (fw = 140 g/mol) and disodium succinate (fw = 162 g/mol) must be added to 1 l of water to produce a solution with a ph 5.28 and a total solute concentration of 100 mm? (assume the total volume remains 1 liter, answer in grams monosodium succinate, grams disodium succinate, respectively.) volumes of 0.05 m nah2po4 and 0.05 m na2hpo4 (pk's for phosphoric acid are 2.15, 6.82 and 12.38). which of the following best describes the resulting solution?
