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

The Arrhenius theory focuses on what ions are produced when a substance is dissolved in water:

• An Arrhenius acid increases the concentration of hydrogen ions (\(\text{H}^+\)) in aqueous solution.
• An Arrhenius base increases the concentration of hydroxide ions (\(\text{OH}^-\)) in aqueous solution.

Step 2: Define a Proton Acceptor

The definition of acids and bases in terms of protons (\(\text{H}^+\) transfer) belongs to the Brønsted-Lowry theory:

• A Brønsted-Lowry acid is a proton donor.
• A Brønsted-Lowry base is a proton acceptor.

Step 3: Evaluate the Statement

The statement claims that "An Arrhenius base is a proton acceptor."

Because "proton acceptor" is the definition of a Brønsted-Lowry base, not an Arrhenius base, the statement is false.

Answer:

False
