The formation constant, Kf, of PbCl42-(aq), Pb2+(aq) + 4 Cl-(aq) ⇌ PbCl42-(aq), is 2.5 x 1015. What are the equilibrium concentrations of Pb2+(aq), Cl-(aq), and PbCl42-(aq) if we add 0.123 mol of Pb(NO3)2 to 1.000 L of a 0.802 M aqueous solution of NaCl? Assume the volume remains fixed at 1.000 L.

Question 1: We place 0.895 mol of a weak acid, HA, and 13.0 g of NaOH in enough water to produce 1.00 L of solution. The final pH of this solution is 4.01 . Calculate the ionization constant, Kb, of A-(aq). Question 2: HA is a weak acid with a pKa value of 3.76 . What is the pH of a buffer solution that is 0.359 M in HA and 0.844 M in NaA?

Reaction (i) Pb2+(aq) + 2 Cl-(aq) ⇌ PbCl2(s) If NaOH is added to reaction (i), a second precipitation reaction will occur: Reaction (ii) Pb2+(aq) + 2 OH-(aq) ⇌ Pb(OH)2(s) The important aspect of this is that the two reactions take place within the same container (just because we draw them separately on paper does not mean they are separate inside in the container). Thus, reaction (i) and (ii) are coupled at the molecular level by a common chemical species that...

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...
