Question

Why are we preparing a standard solution series? What will it be used to calculate? How many milliliters of a 1.30 M NaCl solution are needed to prepare 0.50 L of 0.10 M NaCl? When preparing aqueous a volumetric flask, does it matter if there are a few droplets of water in solutions in the bottom of the flask or does the flask need to be completely dry? Explain? Recall Beer's law, A = e^- lc. In your experiment, a calibration plot of _________ (Y) versus _________ (X) will be constructed. For the unknown penny solution, _________ will be measured and _________ will be calculated using the calibration curve.

Explanation / Answer

Ans 1 . Standard solutions are made from the known amount of solute and measured volume of solvent .

Since the molarity or concentrations of these solutions are known before hand , these can be used to determine the concentrations of the unknown solution in the experiment .

These are basically used in titration reactions , to determine the molarity .
