Calculate the [SCN-] solution A, where 5.7 mL of 2.910?3 M NaSCN is diluted to 44.0 mL with 0.1 M Fe(NO3)3. Next calculate the [FeSCN2+] in the solutions prepared by diluting volumes of solution A with 0.1 M Fe(NO3)3 to a final volume of 1.0101 mL. Do this for 1.0, 3.0, 5.0, 7.0, and 9.0 mL. Keq[Fe3+] = [FeSCN2+]/[SCN?]
Calculate the pH at the equivalence point for the titration of 0.230 M methylamine (CH3NH2) with 0.230 M HCl.
In a titration, 10.0 mL of 0.025 M hydrochloric acid is added to 30.0 mL of 0.030 M ammonia. What is the pH of the resulting mixture?
An acid solution is 5.00% HCl by mass. Assuming that the density of the solution is 1.0 g/mL, find the molarity of the hydrogen ion in the solution. The molar mass of HCl is 36.5 g/mol
Write the net ionic equation to show the formation of a precipitate (insoluble salt) when the following solutions are mixed. Write noreaction if no insoluble salt forms KCl(aq)+Pb(NO3)2(aq)
The accepted value (mu) for a standard sample of chloride was 34.63 percent chloride. Triplicate analysis of this material by a new procedure yielded a mean value of 34.71 and an estimated standard deviation of 0.04
A calibrated flask was filled to the 25 mL mark with ethyl alcohol. By weighing the flask before and after adding the ethyl alcohol, it was determined that the flask contained 19.7325 g of alcohol.
