P6C.4 State what is expected to happen to the cell potential when the specified changes are made to the following cells. Confirm your prediction by using the Nernst equation in each case. (a) The molar concentration of silver nitrate in the left-hand compartment is increased in the cell Ag(s)|AgNO3(aq,m₁)||AgNO3(aq,m₁)|Ag(s). (b) The pressure of hydrogen in the left-hand compartment is increased in the Pt(s)|H₂(g‚ð₁)|HCl(aq)|H2(g,p₁)|Pt(s). (c) The pH of the right-hand compartment is decreased in the cell Pt(s)|K¸[Fe(CN)6](aq),K₁[Fe(CN)6](aq)||Mn²*(aq),H*(aq)|MnO2(s)|Pt(s). (d) The concentration of HCl is increased in the cell Pt(s)|Cl2(g)|HCl(aq)||| HBr(aq)|Br2(1)|Pt(s). (e) Some iron(III) chloride is added to both compartments of the cell Pt(s)| Fe3+(aq),Fe2(aq)||Sn**(aq),Sn²+(aq)|Pt(s) (f) Acid is added to both compartments of the cell Fe(s)| Fe²+(aq)||Mn²+(aq), H(aq)|MnO2(s) Pt(s).
