What is an acid in terms of Arrhenius theory?
An acid, according to Arrhenius theory, is a substance that dissociates in water to give hydrogen ions (H+).
Define a base according to Arrhenius theory.
According to Arrhenius theory, a base is a substance that dissociates in water to give hydroxide ions (OH-).
What is the formula for the pH of a solution?
The formula for the pH of a solution is pH = -log[H+], where [H+] represents the concentration of hydrogen ions in the solution.
Explain the concept of conjugate acids and bases.
Conjugate acids and bases are related pairs where a base can accept a proton to form its conjugate acid and an acid can donate a proton to form its conjugate base.
Differentiate between a strong acid and a weak acid.
A strong acid completely dissociates in water, releasing all its hydrogen ions, while a weak acid only partially dissociates, releasing a small fraction of its hydrogen ions.
