Determine the Amount of Nitrogen in Water Samples.

Use Color Transition of Titration to Determine Water Hardness.

Prepare a flask containing a yellow solution, as you mix it on a magnetic stirrer the solution will turn from yellow to blue and back to yellow.

This kit allows analysts to perform a very simple titration to determine the alkalinity and the phenolphthalein of their fresh water sample.

With this kit, students determine dissolved oxygen concentration without a meter.
