We finished the Standardization / Unknown Molar Mass of an Acid lab today. Make sure that all calculations for the lab are complete and ready to turn in tomorrow. Also, solve problems 55 and 56 on page 183 of the book as part of the lab analysis.
From the previous homework assignment, the answers to question 51 are: [Na+1]=2.50M; [NO3-1]=.250M; [OH-1]=2.25M (Which makes the solution basic.); and [H+1]=0
For #52, [H+1] is limiting, thus the concentration is 0. [OH-1]=.020M. The resulting solution is basic.
For #53, [HCl]=.102M
