The textbook procedure is asking you to dissolve 1 g of 3-nitrophthalic acid in hydrazine and only then to add the triethylene glycol. in the lab the instructor will tell you to add the triethylene glycol from the very beginning together with hydrazine. what would be a good reason to introduce such change? select one: a. 3-nitrophthalic acid is not readily soluble in aqueous hydrazine but it is soluble in organic solvent, triethylene glycol b. triethylene glycol gives two oh groups to the 3-nitrophthalic acid c. 3-nitrophthalic acid reacts with hydrazine too vigorously if the triethylene glycol is not added d. hydrazine should react with triethylene glycol prior reacting with 3-nitrophthalic acid

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution. calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
