question 6

an arrhenius base is a proton acceptor.

true
false

Explanation:

🆕 New Concept Discovered: Acid-Base Theories
Comparing Arrhenius and Brønsted-Lowry definitions.

Step 1: Define an Arrhenius Base

According to the Arrhenius theory, definitions are based on what ions are produced in an aqueous (water) solution:

• Arrhenius Acid: A substance that increases the concentration of hydrogen ions (\(\text{H}^+\)) in water.
• Arrhenius Base: A substance that increases the concentration of hydroxide ions (\(\text{OH}^-\)) in water.

Step 2: Define a Proton Acceptor

The concept of "proton transfer" belongs to a different theory, the Brønsted-Lowry theory:

• Brønsted-Lowry Acid: A proton (\(\text{H}^+\)) donor.
• Brønsted-Lowry Base: A proton (\(\text{H}^+\)) acceptor.

Step 3: Compare the Statement

The statement claims that an Arrhenius base is a proton acceptor.

• An Arrhenius base is defined by producing hydroxide ions (\(\text{OH}^-\)).
• A proton acceptor is the definition of a Brønsted-Lowry base.

Because the statement mixes the Arrhenius name with the Brønsted-Lowry definition, the statement is false.

Answer:

False
