Your titration involves using a 25.00mL pipette to deliver the ascorbic acid standard solution (C6H₂O6) to the conical f
Now that you have calculated the mass of ascorbic acid required to prepare a 250mL standard solution at a concentration of 0.005mol/L, what glassware would you use to make the solution up in? 0.250L conical flask 0.250L beaker 0.025L conical flask 0.250L volumetric flask
What is the number of moles of ascorbic acid present in a 250mL solution with a concentration of 0.005mol/L? On = 0.02 O n = 1.25 x 10-3 n = 1.25 O n = 2.0 x 10-5
What is the mass of ascorbic acid (C6H8O6) required to prepare a 250mL solution with a concentration of 0.005mol/L? (Hint: in the last few questions you have already determined the two equations needed, the number of moles of ascorbic acid required, n, and its molar mass, M.) This mass will be in grams. The answer must be written as a digit to four decimal places without units.
You are about to perform a titration with your standard solution (solution of exactly known concentration) of ascorbic acid and a solution of iodine of unknown concentration. Answer the following statement true or false. The burette you use can have drops of water in it from washing without affecting the results. (Hint: if you need the concentration or volume of a solution in your calculations, you cannot allow these things to change by using wet or unclean glassware.) True O False
