Heyyy beautiful chemistssss, can you all please give me few ideas of EASY experiments I could do for my UNIT 2 chemistry sac, in which we have to do experiment relating to water (e.g pH, quality etc), I'm looking for something reallyyy easy i.e easy to measure & record data, and talk about it.

We're doing an experiment right now about purifying a water sample with copper sulfate. You could use gravimetric analysis (vacuuming the pure water out) or distillation (heating it up) and then use UV-Visible spectroscopy to check if it's pure after making a precipitate (copper hydroxide).
