Try this practical with your students to measure the hardness of water samples and investigate the effect of boiling. Includes kit list and safety instructions.In this experiment, you will determine the “hardness” of a water sample by complexometric titration. Learning Objectives Apply concepts of complexation chemistry to determine the calcium concentration of a hard water sample.
Hard water does not mix well with soaps. Because of this, you can test for the hardness of water by looking at the amount of bubbles produced when you mix water and soap. Aim: To test various solutions of water for hardness and see how effective different filtering In this guide, we take you through the 4 best ways to test water hardness: checking with your water supplier, the soap buds test, a DIY testing kit, and sending a water sample to a lab. We also take a close look at the main issues hard water can cause. Soft water: 0-60 mg/L. Medium hard water: 60-120 mg/L. Hard water: 120 mg/L and above. Water hardness impacts many experiments and processes, so water hardness testing is required in laboratories and industrial production. Carbonate and non-carbonate hardness. There are several ways to test your water’s hardness, including checking the water quality report, using DIY test kits, sending a water sample to a professional laboratory, and performing the soap suds test.
