Step 2
Evaluate Each Option
Answer
A. Sodium nitrate: Dissolves in water but does not produce OH⁻ ions, thus not an Arrhenius base.
B. Sodium sulfate: Also dissolves in water but does not provide OH⁻ ions. Therefore, it is not an Arrhenius base.
C. Sodium chloride: Dissolves in water and forms Na⁺ and Cl⁻ ions, without producing OH⁻ ions. It is not an Arrhenius base.
D. Sodium hydroxide: Dissociates in water to produce Na⁺ and OH⁻ ions, thereby increasing the concentration of hydroxide ions in the solution, making it an Arrhenius base.
