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; 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 each reagent and the volume of water that must be added for dilution.

Question

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; 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 each reagent and the volume of water that must be added for dilution.

a. Chlorine water
b. Bromine water.
c. Iodine water

What I need help with is how do I solve for this question? Do I use dilution calculations to solve for a,b,c?

It's the reactions: 6H++ BrO3-+ 5Br- --> 3H2O+ 3Br2 2 Cu2+ 4I--> 2CuI + I2 2H++OCl- +Cl- --> Cl2+H2O
