A(n)__is a solute that dissociates to release hydrogen ions, and a(n)___is a solute that removes hydrogen ions from solution.
(a) base, acid
(b) salt, base
(c) acid, salt
(d) acid, base

Verified step by step guidance

1. Understand the definitions of the key terms: An acid is a solute that dissociates in solution to release hydrogen ions (H\_3O\^+ or H\^+), increasing the acidity of the solution.
2. A base is a solute that removes hydrogen ions from the solution, often by accepting H\^+ ions or releasing hydroxide ions (OH\^-) that combine with H\^+ ions.
3. Identify which term corresponds to releasing hydrogen ions: this is the acid.
4. Identify which term corresponds to removing hydrogen ions: this is the base.
5. Match these definitions to the options given to select the correct pair: acid for releasing H\^+ ions, and base for removing H\^+ ions.

Key Concepts

Acid

An acid is a substance that dissociates in water to release hydrogen ions (H+). These ions increase the solution's acidity, lowering its pH. Common examples include hydrochloric acid (HCl) and sulfuric acid (H2SO4).

Base

A base is a substance that removes hydrogen ions (H+) from a solution, often by releasing hydroxide ions (OH-) that combine with H+ to form water. Bases increase the pH of a solution, making it more alkaline. Examples include sodium hydroxide (NaOH).

Dissociation in Aqueous Solutions

Dissociation refers to the process where compounds separate into ions when dissolved in water. Acids dissociate to release H+ ions, while bases dissociate to release OH- ions or remove H+ ions. Understanding this process is key to identifying acids and bases.
