Thanks Borek!, You are right, but I need to know the exact amount of the products and that's because the reaction will not yield 100% of the expected products. How can I do this? Maybe with titration? or what about my initial proposition of extrapolating the results from the HCl solutions to measure the concentration of the Cl- ions in the hydrolysis of 2-chloro-2-methylpropane?
Thanks for your answers! All ideas are very welcome!
