What did you learn from this lab about water and about process?

The Water Testing Lab taught me a lot about both ions and water testing. I can now better understand ions and how they work from the demonstration in class by Rachel and also the tests. Water is easily contaminated and can look pure and contain harmful, or just kind of weird elements. You cannot judge solutions by their looks because they often are clear and seem pure. Water being one of the most important solutions on this earth and a common solvent needs to be tested constantly and watched carefully.
