1. Predict how the addition of hydrochloric acid to Ca(OH)2 (s) would affect the equilibrium in Part one of your experiment. Explain your prediction in terms of Le Chetalier's principle. Why would HCl react with Ca(OH)2? Show the reaction(s) 2. Indicators are usually organic molecules with functional groups that will accept protons. This will change the structure and make the molecule change color. Why are these values not included in acid/base equilibrium? 3. Lead (II) chloride (PbCl2) is a white...

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...
