LaMotte Hardness Reagent #7, 60 ml, supports engaging water quality testing activities in chemistry, environmental science, and STEM classrooms. Designed for use in total hardness testing procedures, this reagent helps students explore how dissolved minerals such as calcium and magnesium influence water chemistry.

Through hands-on hardness testing experiments, students learn how scientists evaluate water composition while developing essential laboratory skills such as accurate measurement, titration techniques, observation, and data interpretation. These activities provide a practical way to connect classroom chemistry concepts with real-world applications, including freshwater analysis, environmental monitoring, and aquatic science.

Ideal for middle school, high school, college, and university laboratories, Hardness Reagent #7 helps educators create meaningful investigations into water quality and chemical analysis. Students can compare samples from different sources, analyze variations in mineral content, and better understand the factors that influence water characteristics.

With its convenient 60 ml format, this reagent is a valuable addition to educational laboratory programs focused on water chemistry, environmental science, and STEM learning. LaMotte water testing products help educators provide reliable, hands-on experiences that encourage scientific inquiry and strengthen students’ understanding of analytical testing methods.
