QuestionAnswer What is the definition of an acid according to the Brønsted-Lowry theory? An acid is a substance that donates a proton (H⁺ ion) to another substance in a chemical reaction. How is a base generally defined in the context of acids and bases? A base is a substance that accepts a proton (H⁺ ion) or donates a pair of electrons in a chemical reaction. What is pH, and what is the pH range of acids and bases? pH is a measure of the hydrogen ion concentration in a solution. Acids have a pH less than 7, while bases have a pH greater than 7. What is the significance of the pH scale in understanding acids and bases? The pH scale helps determine the acidity or alkalinity of a solution, indicating how strongly acidic or basic it is. What are some common examples of acids and bases? Common acids include hydrochloric acid (HCl) and vinegar (acetic acid), while common bases include sodium hydroxide (NaOH) and baking soda (sodium bicarbonate). How do acids and bases react with each other? Acids and bases react in neutralization reactions to form water and a salt, often resulting in a pH close to 7. Why is understanding acids and bases important in everyday life and industry? Understanding acids and bases is crucial for processes like digestion, cleaning, manufacturing, and environmental management, ensuring safety and efficiency.
