What defines an acid according to the Brønsted-Lowry theory?
According to the Brønsted-Lowry theory, an acid is a substance that donates a proton (H⁺).
What is the pH of a neutral solution?
The pH of a neutral solution is 7, indicating that the concentrations of hydrogen ions (H⁺) and hydroxide ions (OH⁻) are equal.
What is the relationship between pH and hydrogen ion concentration?
pH is inversely related to the concentration of hydrogen ions (H⁺) in a solution. As the concentration of H⁺ increases, the pH decreases.
Which of the following is a strong acid?
A strong acid completely dissociates in water, releasing all of its hydrogen ions.
What is the conjugate base of HCl?
The conjugate base of an acid is the species that remains after the acid has donated a proton.
What is a buffer solution?
A buffer solution is a solution that resists changes in pH when small amounts of acid or base are added.

What is the conjugate acid of NH₃?
The conjugate acid of NH₃ (Ammonia) is NH₄⁺, which is formed when NH₃ accepts a proton.
What is the pH of a 0.001 M NaOH solution?
NaOH is a strong base, so it will completely dissociate. The pOH can be calculated first and then converted to pH.
What is the primary difference between strong and weak acids?
Strong acids completely dissociate in water, while weak acids only partially dissociate.
