This lab contains a lot of concepts. First, students complete a pre-lab that requires them to name some compounds using a word bank. They don't have to know how to write formulas because they can figure out the formulas using some basic knowledge of elements. The word bank allows them to figure out the formulas. Then, students perform six different reactions. They write observations and identify which indicators are present. They also will write balanced chemical equations using the formulas from the pre-lab.
