student took a sample of vinegar with a 5 ml volumetric pipet and then emptied all of the liquid in an Erlenmeyer flask by blowing out the sample
Homework Answers
Ans: The student might get some error in the result. The measuring equipment should be the same for measuring all liquid. Since the student measure vinegar with the volumetric pipet and other with Erlenmeyer flask, there might be a small error. So a student should take the same equipment for all the cases.

. Student dissolves a tablet of Vitamin C in 100.0 mL of water. 2. Using 5.00 mL volumetric pipet, student transfers 5.00 mL of the tablet solution in to an Erlenmeyer flask. 3. After adding starch indicator, student titrated Vitamin C containing solution with standard solution of Iodine (5.00E-3 M). It took 17.73 mL of Iodine solution. MM of vitamin c = 176.1 g/mol Calculate mass of Vitamin C in the tablet.

Use a volumetric pipet to deliver 2 mL of 4 M sodium hydroxide solution to each of seven 100-mL volumetric flasks. Add 2,4, 6, 8, and 10 mL, respectively, of the salicylic acid stock solution to 5 of the labeled flasks. Calculate the concentrations of the standard solutions. Use a pipet to place 10 mL of the unknown solution into another volumetric flask and label Unknown 1. Dilute each solution to the mark with DI water. The seventh flask that...

1aYou are measuring 10.00mL of liquid with a volumetric pipet. While you are drawing the liquid into the pipet, you remove the tip of the pipet from the solution and suck up a little bit of air into the pipet. You adjust the liquid so that the meniscus is at the calibration line, but you notice there are some air bubbles in the pipet. 1a.) How do the bubbles impact the amount of liquid that you will dispense? Will you...
