This strip can be used to educate students on the difference between “fresh” and “salt” water. It can also be useful in explaining the concepts of freezing point depression and boiling point elevation. In applications where the salt content is high the sample will require dilution with deionized water before running the test. In these cases, the test result will need to be corrected by using a dilution factor to arrive at the final result. Instruction: 1) Dip the strip into water for 1 second. 2) Wait 10 seconds, then compare the test strip to the color chart. *Important! Do not touch the test pad with your fingers.
