Prelab Question...
Obj - Use titration to determine hydroxide concentration in solutions of saturated calcium hydroxide, and from these determine the solubility and solubility product constants for calcium hydroxide in the presence and absence of another solute.
Question is -- You need standard aqueous HCl of about 0.04 M concentration. Explain why you need to dilute a whole-number volume rather than use the precise volume required to give 0.040000 M HCl. For example, assuming you had 0.1164 M HCl you would dilute 75.00 mL to 250.00 mL, rather than diluting 85.90 mL to the same volume.
Homework Answers
A given stock solution can be diluted in series to get the required concentration and this process is called serial dilution. Dilution factor is constant is each step of dilution. Serial dilution is useful to create a accurate highly dilute solution.
