AP Chemistry Update

Today students reviewed their Chapter 4 homework in a way that encouraged collaboration and discussion in small groups. After class discussion, they turned in a worksheet that contained their answers to selected homework problems. Students also did a lab experiment today that was designed to help them strengthen their understanding of the solubility rules. Students mixed various solutions together and observed whether or not a precipitate would form. The homework for Friday is to write the net ionic equations for the precipitation reactions that occurred in the lab. A copy of the lab activity can be found here. Students should read ahead in Chapter 4 and be prepared to discuss acids and bases (Section 4.3).
