Suppose you need to prepare 125.5 ml of a 0.256 M aqueous solution of NaCl. What mass of NaCl do you need to use to make the solution? Answer:
(a) Saturated Sodium Chloride. Watch Video-3a where to 4 mL of saturated (5.4 M) NaCl in a 13 x 100mm test tube, 2 mL of concentrated (12 M) HC) is added. Write down the chemical reaction(s) involved, being sure to include the state of matter of all reactants and products so it is clear if there is a solid/precipitate expected.
