describe the preparation of 12 ml of a 0.050 M solution of each of the halogens, using the reactions in the preceding question. Available to you are solid Ca(OCl)2; 1.20 M solutions of NaCl, 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 each reagent and the volume of water that must be added to dilutions.
