Question

question 1 (5 points)
a ph buffer will fluctuate dramatically in ph.
a) true
b) false
question 2 (5 points)
a titration can be used to neutralize an acid with a base
a) true
b) false
question 3 (5 points)
all acids are strong acids.
a) true

Explanation:

• Question 1: A pH buffer resists large changes in pH. It contains a weak acid - conjugate base or weak base - conjugate acid pair. When small amounts of acid or base are added, the buffer components react to minimize the pH change. So, the statement "A pH buffer will fluctuate dramatically in pH" is false.
• Question 2: Titration is a process where a solution of known concentration (titrant) is added to a solution of unknown concentration (analyte) until the reaction is complete. In acid - base titration, an acid can be neutralized by a base (or vice - versa) at the equivalence point. So, the statement "A titration can be used to neutralize an acid with a base" is true.
• Question 3: Acids are classified as strong or weak. Strong acids (e.g., HCl, HNO₃) completely dissociate in water, while weak acids (e.g., CH₃COOH) only partially dissociate. So, the statement "All acids are strong acids" is false.

Answer:

1. b) False
2. a) True
3. b) False
