Choose which of the following is false.
A
Acids are proton acceptors
B
Buffers work to neutralize the pH of a solution
C
The pH scale is a measure of the acidity of a solution
D
Bases are proton acceptors
Verified step by step guidance1
Understand the definition of acids and bases: Acids are substances that donate protons (H+ ions) in a solution, while bases are substances that accept protons.
Review the concept of buffers: Buffers are solutions that resist changes in pH when small amounts of acid or base are added. They do not neutralize the pH but rather maintain it within a narrow range.
Examine the pH scale: The pH scale measures the acidity or basicity of a solution, ranging from 0 (most acidic) to 14 (most basic), with 7 being neutral.
Identify the false statement: Based on the definitions, determine which statement incorrectly describes the properties of acids, bases, or buffers.
Conclude that the statement 'Acids are proton acceptors' is false, as acids are actually proton donors.
