Agua dura y agua blanda

Water contains dissolved mineral ions like sodium, calcium, and magnesium, affecting its hardness or softness. Hard water, rich in calcium and magnesium, is beneficial for drinking but can cause appliance issues due to lime precipitation. Soft water, with high sodium content, is ideal for cleaning. The mineral content in water influences daily experiences and varies based on geological factors.
