1. How would doubling the concentration of NaOH used for the titration affect the calculated rate constant? 2. What makes the "blank" titrimetric determination different from the reaction you will be preforming?

Expert Solution

1. The rate constant is independent of the concentration of the reactants and products. It is however dependent on the nature of the chemical substance, temperature and the presence of catalyst.

So if we alter the concentration of NaOH, there won't be any effect on rate constant.

Moreover, rate constant is a proportionality between the rate of the reaction and the concentrations raised to the power of it's orders.

2. In blank titrimetry there is no analyte taken. Or the species which is to be determined is absent. It is just taken to correct the error if any. In the reaction medium there may be interfering ions due to which our titration volume may change. So a blank helps us remove those errors.

Hope this helped! Have a good day!
