What molarity of aqueous aluminum sulfate solution can be expected to show the same conductivity as 0.030 M CaSO4 at 20,000 units?
The catalyzed reaction took 2 minutes. The non-catalyzed reaction took 30. Solutions in each consisted of 5 mL phosphate citrate buffer
The relationship of [A]t / [A]o = 0.50^n, where n=number of half lives. n = I understand that the linear plot of 1/[C4H6] means second order.. but i do not understand how to calculate the half life from this information for part b.
Part A. At 25°C, another student has the following data for the aluminum cylinder. The uncertainty in mA, mB, and mcyl is 0.001 g.
Suppose that you have 175 mL of a buffer that is 0.300 M in both benzoic acid (C6H5COOH) and its conjugate base (C6H5COO%u2013). Calculate the maximum volume of 0.250 M HCl
