Water-based solutions are mixtures where water acts as the primary solvent. These solutions can dissolve various substances, such as salts, sugars, and acids, making them essential in many applications. They are commonly used in cooking, cleaning, and industrial processes due to their effectiveness and safety. In addition to everyday uses, water-based solutions are crucial in scientific research and pharmaceuticals. For example, biological experiments often require water-based solutions to maintain the right environment for cells and microorganisms. Their versatility and non-toxic nature make them a preferred choice in many fields.
