Consider the following graph

1. The shape of boron trihydride, BH3, is 2. In an exothermic reaction, the potential energy of the products is than the potential energy of the reactants. 3. A system at equilibrium always has forward and reverse reaction rates which are 4. A solution at 25°C with a pOH of 3.45 has a pH of 5. When nitric acid is titrated to an end point by lithium hydroxide, two products are and O 6. The standard reduction potential table lists the Evalues of half-cell reactions measured in combination with the standard half-cell.

4. Given: a) X 3+ + W → reaction Z 2+ + 2e- → Z b) V 2+ + Y → no reaction Y 2+ + 2e- → Y c) Z 2+ + V→ reaction V 2+ + 2e- → V d) Y 2+ + Ag → no reaction W + + e- → W e) Y 2+ + Z → reaction X 3+ + e- → X 2+ Write and label the five redox equations just as you did in your lab write up. Make a redox table of the five half-reactions.

The solution being added is called the titrant, and we say that it solution. The completion of the reaction is usually shown by a change of color caused by a substance called an indicator. used titrate the other A typical titration proceeds in the following way. A specific volume of the solution to be titrated is poured into an Erlenmeyer flask. For example, 15.0 mL of a sulfuric acid solution of unknown concentration is added to a 250 mL Erlenmeyer flask. An indicator is then added to the flask, which changes color when the reaction is complete. The titrant in this example is potassium hydroxide, having a concentration of 0.121 M. The titrant is added to a buret. After slowly adding the titrant to the flask, the reaction…
