Suppose that you have a supply of each of the acids listed in Table 11.1 and each of the bases listed in Table 11.2, as well as 1.00 M HCl solution and 1.00 M NaOH solution. Describe how you would prepare 1.00 L of an effective buffer solution at each of the following pH values. Specify (i) which acid or base you would use (in each case, use 0.100 mol) and (ii) whether you would add HCl or NaOH, and how much. (a) pH = 2.50 (b) pH = 7.00 (c) pH = 11.75
What is the rate constant for the reaction at 85°C?
Calculate the molar solubility of AgBr in a 1.00 M aqueous solution of ammonia. Then calculate the solubility of AgBr in pure water, and compare the two solubilities. (Ksp for silver bromide is 7.7x10 -13 and Kf for Ag(NH3)2+ is 1.6x10^7)
Calculate the pH of a solution that is .150 M in sodium formate and .200 M in formic acid (Ka=1.8*10^-4)
A sample of neon gas is held in a rigid 1.814L container with a pressure of 1.273atm at 25 C. 3.193g of an unknown gas is added to the container. The temperature remains constant, but the pressure rises to 2.386atm. What is the molar mass of the a..
allowed to burn in the presence of 16.00 g of oxygen. How much (in grams) CH4, O2, CO2, and H2O remain after the reaction is complete?
The value of the gas constant is 0.08206 L x atm/(mol x K). You may also find the conversion factors 1 atm = 760 torr and Tk = Tc + 273 useful.
