Potable Water: Standards/ Hardness

💧 Potable Water & Hardness – Basic Concepts with Reactions Hello students 👩‍🔬👨‍🔬 In this short and important video, I have explained the fundamental concepts of potable water and hardness of water, which form the base of Water Technology in Engineering Chemistry. First, we discussed what potable water actually means and the essential drinking water standards recommended by the World Health Organization. You will clearly understand: ✔ What makes water safe for drinking ✔ Physical, chemical, and biological standards ✔ Acceptable pH range and purity requirements Then we moved to an important topic — Hardness of Water 💧 In this video, I have explained: ✔ Definition of hardness ✔ Why hard water does not produce lather easily ✔ The real chemical reason behind soap wastage ✔ Chemical reaction responsible for scum formation This is a short foundational lecture, and in the upcoming videos we will cover: 🔹 Types of hardness 🔹 Temporary & permanent hardness in detail 🔹 Removal methods 🔹 Numerical problems So stay connected for the complete Water Technology series 📚✨ If this video helped you understand the basics clearly, don’t forget to like, share, and subscribe for more Engineering Chemistry lectures.
