Step 1:: Identify the compound LIOH (aq)
LIOH (aq) is lithium hydroxide dissolved in water.
Step 2:: Analyze the compound's components
Lithium (Li) is a group 1 element, which means it readily loses an electron to form a cation. Hydroxide (OH-) is a common anion that can accept a proton.
Step 3:: Apply the Arrhenius definition of acids and bases
According to the Arrhenius theory, acids are substances that donate hydrogen ions (protons) in aqueous solution, and bases are substances that donate hydroxide ions in aqueous solution. In this case, LIOH (aq) dissociates into Li+ and OH- ions in water.
Step 4:: Apply the Bronsted-Lowry definition of acids and bases
The Bronsted-Lowry theory defines acids as proton (H+) donors and bases as proton acceptors. Here, the OH- ion is a strong Bronsted-Lowry base because it readily accepts a proton.
Step 5:: Compare the results with the answer choices
Since LIOH (aq) dissociates in water to form OH- ions, it meets the criteria for being a Bronsted-Lowry base. Additionally, as it dissociates into ions in water, it also meets the Arrhenius definition of a base. Therefore, the correct answer is:
Final Answer
A. both an Arrhenius and Bronsted-Lowry base
