Describe the preparation of 12 mL of a 0.050 M solution of the following halogen, using the reaction below. Available to you are solid Ca(OCl)2; 0.20 M solutions of NaCl, NaBr, NaBrO3, and CuSO4,; a 0.40 M solution of NaI; a 0.50 M solution of H2SO4; distilled water; and a 10-mL graduated cylinder (where volumes can be read to the nearest 0.1 mL). Calculate the required quantity of the reagent and the volume of water that must be added for dilution.
