Question 1: What are the key characteristics of acids and bases in AP Chemistry?
Answer:
– Acids: Characterized by a sour taste, corrosive nature, and ability to react with metals to form hydrogen gas; have a pH below 7.
– Bases: Typically bitter-tasting, slippery to the touch, and react with acids to form salts and water; have a pH above 7.
Question 2: Explain the concept of acid-base neutralization in AP Chemistry.
Answer:
– Acid-base neutralization: A chemical reaction between an acid and a base that results in the formation of a salt and water; the resulting solution has a neutral pH of 7.
– Salt: A compound composed of positively charged ions from the base and negatively charged ions from the acid.
Question 3: Describe the Brønsted-Lowry theory of acids and bases in AP Chemistry.
Answer:
– Brønsted-Lowry theory: Defines acids as proton (H+) donors and bases as proton acceptors;
– Conjugate acid-base pair: An acid-base pair that differs by a single proton;
– Strength of acids and bases: Measured by their dissociation constants (Ka and Kb), which indicate their ability to donate or accept protons.
