UVU is very different from most universities as we do not teach from a textbook. Most instructors have a PhD in engineering and 20-40 years of experience. Course content is developed from scratch and is based on the instructorâs experience. The textbook serves as a reference and some reading assignments are made.
Deionization (DI Water or Demineralization) simply means the removal of ions. Ions are electrically charged atoms or molecules found in water that have either a net negative or positive charge.
Deionized Water (We call it DI water in the chemistry labs) is just what it sounds like: Water that has the ions removed. Tap water is usually full of ions from the soil (Na+, Ca2+), from the pipes (Fe2+, Cu2+), and other sources. Water is usually deionized by using an ion exchange process. Why de-ionize water? Often, when you are doing chemistry experiments, the ions in water will be an interference.
