Questions and Answers

Which statement is true regarding pH levels?

As a solution's pH rises, it becomes more acidic.

A solution with a pH of 5 has more hydrogen ions than a solution with a pH of 8.

A solution with a pH of 10 is neutral.

As a solution's pH rises, it becomes more basic. (correct)

What defines a buffer system?

All buffers are composed of strong acids.

A buffer only works at a pH of 7.

A buffer changes the pH of a solution significantly.

A buffer is a system of chemicals that resists a change in pH. (correct)

Which statement accurately describes the behavior of acids in water?

All acids dissociate in water to give hydrogen ions and an anion. (correct)

Acids produce hydroxide ions when dissolved in water.

All acids are strong and dissociate completely in water.

Some acids do not release hydrogen ions in water.

Study Notes

Acid-Base Chemistry Concepts

A solution with a higher pH is more alkaline, not more acidic; therefore, the statement regarding rising pH becoming more acidic is incorrect.
Buffers play a crucial role in maintaining pH stability in various chemical and biological systems by neutralizing acids and bases.
Acids typically dissociate in water, releasing hydrogen ions (H⁺) and anions; however, not all acids fully dissociate (e.g., weak acids).
A solution with a pH of 10 has significantly fewer hydrogen ions compared to one with a pH of 2; pH decreases by one unit indicates a tenfold increase in hydrogen ion concentration.
