Hint: each solution dilutes the other upon mixing.You are the manager of a chemical stockroom, and find a bottle containing approximately one liter of aclear and colorless solution of unknown identity and concentration. Your only clue to its identity is thatit was found between bottles of silver fluoride and sodium fluoride, so it is likely an aqueous solution ofone of those two compounds. You will need to develop a procedure to determine the following:a) The identity of the unknown solutionb) The concentration of the unknown solutionWrite out a precise procedure, which includes all glassware, reagents, and steps. You will also need towrite the calculations that you would need to determine the concentration of the solution. Assume thatyou have access to any reagent you might need. You may also assume that you have access to commonlaboratory equipment. You observed some examples of laboratory equipment within the VirtualChemistry Laboratory simulations. You may visit the virtual lab at chemcollective.org to refamiliarizeyourself with…You are presented with a white solid and told that due tocareless labeling it is not clear if the substance is bariumchloride, lead chloride, or zinc chloride. When you transferthe solid to a beaker and add water, the solid dissolves to givea clear solution. Next a Na2SO41aq2 solution is added anda white precipitate forms.
