Draw out a cell for Al in Al(NO3)3 and Ag in AgNO3. Label the anode and cathode sides, including charge on each electrode. (hint: use a table of standard reduction potentials). Indicate direction of electron flow. Write the net reaction, and the half reactions. What is the standard cell potential? Indicate for both electrodes whether they are dissolving, growing, or staying the same size. Assuming the salt bridge contains KNO3, indicate flow of ions into and out of salt bridge....

Polyprotic acids have more than one proton to donate to water, therefore have more than one equilibrium constant for proton donation. For phosphoric acid, there is a three-step equilibrium: H, PO +H,0 5 H2PO4 + H30* H,PO," +H,0 5 HPO - +H30* HPO 2- +,0 5 PO.- +,0* Kai = 7.11 x 10-3 Ka2 = 6.32 x 10-8 Ka; = 4.5 x 10-13 For all conjugate acid base pairs: K, XKK where K is for the reaction...
