Recently, (in this past week) AP Chem has done a cation/anion identification lab. The primary objective was to learn to identify various cations and anions. What a surprise. In actuality, most of the lab was spent cleaning. Test tubes were being used left and right, and to keep the number of test tubes used under the six each group of two was allowed... let's just say we used more soap than it takes to clean a shower and leave it at that. The greatest challenge was keeping all the substances straight, because there was this tube of something, then this tube of something else, and this tube of another thing.
Also, centrifuge. That which will never be forgotten.
Now, on Friday, AP Chem began a titration lab. Getting the right shade of light pink was hard. The greatest problem was making sure one drop meant one drop.
