The following questions deal with making solutions and using volumetric glassware. (you should review the information on volumetric glassware in the lab equipment section of your lab manual and the videos "using an analytical balance", "using a volumetric flask" and "pipeting techniques".)
(a) what are the standard ways to make a solution of known concentration? (select all that apply.)
dissolve a weighed amount (known mass) of stock solution into a known volume of liquid.
dissolve a known volume of solid into a known mass of liquid.
dilute a known volume of stock solution into a known volume of liquid.
dissolve a weighed amount (known mass) of solid into a known volume of liquid.
(b) volumetric flasks are built a known volume of liquid to an accuracy of about % of the flask's capacity.
(c) most pipettes are built a known volume of liquid.
(d) volumes obtained with volumetric flasks, pipettes, and burets are recorded to the nearest ml.
