What is the importance of pH in daily life?

pH affects many aspects of daily life. In the human body, a stable blood pH (~7.4) is essential for health. Soil pH affects crop growth; acidic soil is treated with quicklime. pH of drinking water should be neutral; too acidic or basic is harmful. In the stomach, low pH helps digestion; antacids neutralize excess acid. pH is also monitored in swimming pools, aquariums, and industry. Soap, shampoo, and skincare products are pH-balanced to avoid skin irritation. Thus, maintaining appropriate pH is vital in health and environment.
