Constant boiling HCl has a concentration of 11.6 M. Yourlaboratory assistant is going to dilute this acid for you to createa stock solution of HCl for you to use in this experiment. Whatvolume of the 11.6 M HCl must the assistant add to one litervolumetric flask so that the concentration of the stock solutionwill be 0.62 M after dilution to the mark the water?
What is the pH of this stock solution?
You will now use this 0.62 M HCl solution to carry out a seriesof dilutions, measuring the pH of each diluted sample. Calculatethe [Cl-] and [H+] concentrations and the pH of eachsample.
Sample A will be produced bby pipetting 1.00 mL of the stocksolution into a 25 mL volumetric, and diluting to the volume withdistilled water.
