Acidic solutions

Acidic solutions are liquids that have a pH less than 7, indicating they release hydrogen ions (H⁺) when dissolved in water. These solutions can taste sour (like lemon juice or vinegar), react with metals, and turn blue Litmus paper red. Acids are common in nature and industry, playing roles in digestion, cleaning, and manufacturing. Their strength varies, with strong acids fully dissociating in water, while weak acids do so partially. Understanding acidity helps in controlling chemical reactions and ensuring safety in various applications.
