Calculate the standard electrode potential for the redox reaction that occurs when a silver electrode is placed in a solution containing 0.1 M Ag+ ions and a platinum electrode is placed in a solution containing 0.1 M H+ ions at standard conditions. The reduction half-reaction for Ag+ is Ag+ (aq) + e- → Ag(s), and the reduction half-reaction for H+ is H+ (aq) + e- → 1/2 H2 (g).

Ammonia and hydrochloric acid react to form ammonium chloride according to the equation: NH3(g) + HCl(g) ⇌ NH4Cl(s). If a student were to add 0.1 moles of NH4Cl to the mixture at equilibrium and the volume of the container is constant, what will be the new concentration of NH3(g) and HCl(g) in the mixture?

A chemistry student needs to determine the effect of adding NaCl to a solution containing AgNO3 at equilibrium. The original solution had concentration [Ag+]=0.01M and [NO3-]=0.01M, and Ksp=1.8x10^-10. How much NaCl (in grams) is needed to be added to the solution in order to decrease the [Ag+] concentration by a factor of 10?
