The steps for determining the concentration of a sample of hydrochloric acid are listed below :Step (1): A 0.1038 M standard sodium carbonate solution was prepared by dissolving 2.750 g ofanhydrous sodium carbonate solid in deionised water and made up to 250.0 cm3.Step (2): 25.0 cm' of the standard solution obtained in Step (1) was transferred to a clean conical flask andthen a few drops of methyl orange were added.Step (3): The sample of hydrochloric acid was put into a burette. The standard solution in the conicalflask was titrated with the hydrochloric acid.Step (2) and Step (3) were repeated for several times.

(a) You are about to prepare three solutions of 0.5 M KI, 0.01 M K2S2O8, and 0.01 M Na2S2O3*5H2O in 250 mL volumetric flasks. - Describe how you will go about this, i,e, explain all steps of weighing of solutes, volumetric measurements (filling up with deionised water) ect. Calculate what mass of solute you will need in each of solutions mentioned above that you need to prepare. Show all calculations steps. (b) You are also tasked to fill burettes with the above-mentioned solutions, however, after filling up the solutions, you realised that there is a bubble towards the bottom tip inside the burette. Is it wise to continue with the experiment, while there is a bubble, if NOT explain why. (c) According to the manual's Experimental procedure, one conical flask (flask 1) contains a mixture of 20 mL of the KI solution plus 10 mL of the Na2S2O3 solution, while in the second flask (flask 2) there is 20 mL of the K2S2O8 solution with added five drops of starch solution.
