Unformatted text preview: [CH 2 ClCOO-]/[CH 2 ClCOOH]) at 25 ºC. For each concentration, do the calculation both exactly (i.e. using the quadratic equation), and using the approximation that the extent of reaction is small compared to the initial concentration of acid. Over what range is the approximation valid? Initial concentrations are: (a) [CH 2 ClCOOH] = 1.000 M (b) [CH 2 ClCOOH] = 0.500 M (c) [CH 2 ClCOOH] = 0.100 M (d) [CH 2 ClCOOH] = 0.010 M...
