A sample of anhydrous NaHCO3 (FM = 84.007) is suspected to be contaminated with either NaOH (FM = 39.997) or Na2CO3 (FM = 105.989). To verify the suspicion, a 0.7483 g sample was dissolved to prepare a 50.00 mL solution, and a 10.00 mL aliquot was taken to prepare a 100 mL solution, where 25.00 mL was analyzed using double flask method. If the sample requires 0.45 mL of standard 0.0125 N HCl to reach the phenolphthalein endpoint and 35.95 mL to reach the bromcresol green endpoint, calculate the percentage composition (in %w/w) of all the basic components in the sample.
The ethyl mercaptan (C2H5SH, 62.13 g/mol) concentration in a mixture was determined by shaking a 1.534 g sample with 50.0 mL of 0.01293 M I2 in a tightly stoppered flask: 2 C2H5SH (aq) + I2 (aq) --> C4H10S2 (aq) + 2 I- (aq) + 2 H+ (aq) The excess I2 was back-titrated with 15.72 mL of 0.01425 M Na2S2O3: I2 (aq) + 2 S2O32- (aq) --> 2 I- (aq) + S4O62- (aq) Calculate the percentage of ethyl mercaptan in the sample (3 sf)
