  • Solved 2. Below are measurements being made on a device - Chegg
    You will be making measurements on a buret in the lab in Unit 2 Burets are unique because they read upside down; zero (OmL) is on the top and the numbers increase as you go down Instead of reading how much liquid is in the buret, we read how much empty space there is from the top (0 ml) to the meniscus because we are reading how much liquid
