2. In order to analyze a commercial H O solution using the procedure in this experiment, it must first be diluted with distilled water. Consider 10.0 mL of a commercial peroxide solution measured with volumetric pipet diluted to 100.0 mL in a volumetric flask. If 25.00 mL of the diluted solution is titrated with 0.0202 M MnO4, calculate the percent H2O2 in the commercial peroxide solution, i.e. before dilution. The initial buret reading was 0.08 mL, and the final reading...

You have 659.3 mL of a stock solution 4.660 M HCl. For a particular experiment, your lab partner prepared a diluted solution for you to use. In her notes, you read: " Using a volumetric pipet, took 246.54 mL of stock solution and diluted it to 739.21 ml in a volumetric flask. Then, took 100.00 mL of that solution and diluted it to 194.63 mL in a second volumetric flask. " What is the concentration that you should report for...

1. (a) A student is diluting a stock solution of a Vitamin C solution. The concentration of the stock solution is 3.687X10 M. 4.00 ml of the stock solution was transferred into a 50 mL volumetric flask and diluted to the mark with water. What is the final concentration of the dilute Vitamin C solution? (Refer to page 70 in the lab manual). (b) Would a solution prepared the same way but with 2.00 mL of the stock solution have...

You must read the experiment and then answer these questions. 1. Look at the procedure for using a pipet. Why should you not force the last remaining amount of liquid out of the pipet? 2. If you have a 50.00 mL volumetric flask (a flask marked at a specific volume) and a pipette that measures up to 10-mL with marks to the nearest 1/10 mL, how much solute would you add to the flask to make 50.00 mL of a...

2. A stock solution of 1.24 x 10^-4 M dye is available in the laboratory. What volume of the stock solution must be transferred to the volumetric flask to prepare a 25.00 mL dilution with a concentration of 2.00 x 10^-5 M? 3. Perhaps the volume in question 2 is an inconvenient fractional amount. What volume should the analyst dispense to simplify the preparation of the dilution?

Pure solid NaH2PO4 is dissolved in distilled water, making 100.00 ml of solution. 10.00ml of this solution is diluted to 100.00 ml to prepare the original phosphate standard solution. Three working standard solutions are made from this by pipetting 0.8ml, 1.5ml and 3.0 ml of the original standard solution into 100.00 ml volumetric flasks. Acid and molybdate reagent are added and the solutions are diluted to 100.00 ml. You may assume that all these absorbance measurements have already been corrected...
