What part of the procedure allows you to assume that the pressure inside the test tube is equal to the air pressure outside the Test tube
The initial concentrations of Pb2+ and Ag+ are 0.05M and for Cl- 1.5M. Assume all the present Pb2+ and Ag+ precipitate out of solution. Use the remaining Cl- concentration and the Ksp and Kf reactions for AgCl and AgCl2-, respectively, to determin..
A solution of hydrochloric acid has a volume of 250. mL and a pH of 1.92. Exactly 250. mL on 0.0105 M NaOH is added. What is the pH of the resulting solution?
multiply this new K value for reaction 3 by the k value for reaction 2 to "add" the k values together in order to determine the K value of reaction 1.. From the K value of reaction 1, i converted it to E standard. would this be the correct way to ..
