Sophomores in chemistry 1 are working on a three-day lab. They’ve been learning how to use their math skills to find limiting reactants and percent yield, but now they're applying that experimentally. They mixed potassium iodide and lead nitrate, which immediately react to form the bright yellow solid lead iodide. Today they’re doing a filtration to separate the yellow solid from the liquid. Next week, they’ll figure out how much solid was formed during a reaction and compare it to how much they
