why do we use deionized water in an experiment
Deionized water is a common component of a chemistry laboratory and in the manufacturing industry. Understanding how and why this water type is preferable to simple tap water can help you to understand its importance in providing you with the best manufacturing and chemical results. Water that comes from your faucet contains ions that are naturally found in the soil, according to the Illinois Department of Physics. Examples of these ions include sodium, calcium, iron and copper. In deionized water a specialized process is used to remove these ions. An estimated 4 to 6 gallons of tap water are required in order to produce just 1 gallon of deionized water, according to the IN USA Corporation, a chemical instrumentation company.
Deionized water utilizes specialized resins to perform exchanges в such as one resin molecule for every sodium, iron or other ion. Once the exchange is complete, no further ions remain and water is deionized and ready for use. Using deonized water in the chemistry laboratory is important because the ions found in water can affect your experiments. Incorporation of these ions, even if in only small amounts, can cause your experiments to receive false results в or to not work at all.
Deionized water is the water of choice in many factory and manufacturing settings, because manufacturers want to avoid the buildup of salts on machinery. Deionized water may be used to cool, lubricate machines as well as other applications in an industrial setting. Deionized water can be used to manufacture cosmetics, medicines and also process foods. While you can drink deionized water, not all deionized water is suitable for public consumption, according to the Illinois Department of Physcics.
This is because deionized water in the chemistry laboratory contains specialized resins used to remove the ions. These resins may have harmful effects on the body. However, if the water is labeled for public consumption, it is safe to drink.
WHY USE DEIONIZED WATER INSTEAD OF TAP WATER IN SCIENCE EXPERIMENTS. DEBRA S. STUDENT - Philadelphila, PA It's hard to tell if this is just a homework question or you have an actual interest, but deionized water is pure water without contaminants that might affect your experiments. For example if you are trying to determine if a particular sample solution has some particular element in it, you would mess up your experiment if you diluted the sample with tap water that contained that element.
Ted Mooney, P. E. finishing. com Pine Beach, New Jersey If I remember my good old chemistry days, distilled water is better that deionized water for scientific experiments. It is pure water and no solids, ionized or deionized. - Fort Collins, Colorado This public forum has 60,000 threads.
