From this lab I learned that water isn't 100% pure because there are hidden electrical charges, called ions, inside water. I learned that ions are not visible to humans, but by preforming confirming tests ions can, then, be seen by humans. From this lab I also learned a lot about ions. I also learned that it is essential to wash all equipment before preforming a new test because substances from one test can have a big impact on another test.
