Verified step by step guidance

Step 1: Begin by understanding the concept of 'acquired characteristics'. In biology, acquired characteristics refer to traits that an organism develops during its lifetime, which are not inherited genetically.

Step 2: Recognize that in the context of chemistry, particularly acids and bases, acquired characteristics do not apply. Chemical properties are determined by molecular structure and composition, not by traits acquired during the lifetime of a substance.

Step 3: Review the definitions of key terms related to acids and bases, such as dissociation constant (K_a or K_b), pH level, and acid/base strength. These are intrinsic properties based on molecular interactions and cannot be altered by acquired characteristics.

Step 4: Analyze each statement provided in the problem. Statements suggesting that acquired characteristics affect dissociation constants, pH levels, or acid/base strength are incorrect because these properties are determined by the chemical nature of the substance.

Step 5: Conclude that the correct statement is: 'Acquired characteristics are not relevant to the chemical properties of acids and bases.' This aligns with the understanding that chemical properties are inherent and not influenced by external traits acquired during a substance's existence.
