During fourth period on Tuesday, Feb. 4, AP chemistry students began part one of a two-day lab to find the amount of acid present in various juices. The lab required constant observation and careful adjustments, as students slowly dripped a base solution into a colorless one until the faintest shade of pink emerged. Adding a few drops too many would yield an intense shade of pink, which meant the whole process would have to be repeated. In the end, despite several setbacks, every lab group was able to finish within the class period.
