Suppose that you are given four test tubes, labeled A, B, C, and D, each containing a colorless solution. In each of the following questions, indicate which of the solutions included in this experiment could be used to distinguish between the pairs of solutions. In each case, describe the observations you would make and write a net ionic equation for any reaction that would occur.
(a) Test tube A contains 0.1M NaNO3 solution, and Test Tube B contains .1M Ba(NO3)2 solution.
(b) Test tube C contains .1M NaCl solution and Test tube D contains .5M HCl.
