Acid-Base Chemistry

Acid-base chemistry involves substances that either donate hydrogen ions (acids) or accept them (bases). Acids, like lemon juice or vinegar, release hydrogen ions into solutions, making them more acidic. Bases, such as baking soda or soap, accept hydrogen ions, reducing acidity and often creating a bitter taste or slippery feel. The pH scale measures how acidic or basic a solution is, with 7 being neutral, below 7 acidic, and above 7 basic. This chemistry is essential in processes like digestion, cleaning, and industrial manufacturing, helping us understand and control the behavior of different substances.
