Hard and Soft Water

The video explains the concept of water hardness, which is determined by the concentration of dissolved mineral ions like calcium, magnesium, and sodium. Hard water, rich in calcium and magnesium, can cause limescale buildup in appliances but is beneficial for drinking. Soft water, with high sodium content, is ideal for cleaning. The video also covers how water hardness affects daily life and the formation of limescale through precipitation.
