Emphasis should be placed on selected solubility concepts, as probed in part (b) (iii), and on questions such as ìwould Resources for AP Chemistry. In this lecture, we consider how to design a buffer. The volume of container remains constant. Predict the direction of reaction when H 2 is removed from a mixture (lowering its concentration) in which the following equilibrium has been established: H2(g) + I2(g) ↔ 2HI(g) 11. It is a yellow solid at room temperature. Equilibrium in a chemical reaction is when the rate of the forward reaction is the same as that of the reverse reaction. The AP Chemistry curriculum underwent extensive changes beginning with the 2013-2014 academic year. The last page has Chemistry Notes arranged for a regular High School Chemistry course. The equilibrium of a buffer is the same as the equilibrium of the dissociation of an acid.
