1.Will magnesium metal displace Al3+ ion from an aqueous solution

Al³⁺(aq) + 3e^- --> Al(s) E^o=1.68 V

Mg²⁺(aq) + 2e^- --> Mg(s) E^o= -2.36 V

a) No, since E^o cell is positive.

b) Yes, since E^o cell is negavtive.

c) No, the reverse reaction is spontaneous

d) Yes, since ΔG^o is negavtive.

2.The value of K_p for the reaction at 298k.

2SO₂(g) + 2NO₂(g) --> 2SO₃(g) + 2NO(g)

is 0.25. The value of K_p at the same temperature for the reaction

SO₂(g) + NO₂(g) --> SO₃(g) + NO(g)

a) 0.25

b)0.063

c)0.12

d)0.50

± Common-Ion Effect on Solubility for a Metal Hydroxide Consider the dissolution of AB(s): AB(s)⇌A+(aq)+B−(aq) Le Châtelier's principle tells us that an increase in either [A+] or [B−] will shift this equilibrium to the left, reducing the solubility of AB. In other words, AB is more soluble in pure water than in a solution that already contains A+ or B− ions. This is an example of the common-ion effect. The generic metal hydroxide M(OH)2 has Ksp = 4.85×10−12. (NOTE: In...
