Determination of water hardness using a titrator through estimation of the content of CaCO3 in the tested sample.
Complexometric titration
By the end of hardness of water experiment, student will learn to:
Application of Complexometric Titration includes Water Hardness Determination:
Measuring the concentration of calcium (Ca²⁺) and magnesium (Mg²⁺) ions in water to assess water hardness.

I love the idea of virtual labs. It's gonna be something that takes our R&D and work in labs to another level. And I look forward to seeing what PraxiLabs can do with it.

Although there are now several vendors offering virtual reality software for physics labs, there is only one that offers a realistic, I feel like I’m in a real lab solution: PraxiLabs.

PraxiLabs offered my students a chance to actively engage with the material. Instead of watching videos on a topic, they could virtually complete labs and realize the practical applications of class topics. This is a quality alternative to in-person labs.
