Unit 9 Acids and Bases Flashcard

Front

What is a conjugate acid?

Back

A conjugate acid is formed when a Bronsted-Lowry acid gains a proton (H⁺).

Front

What is a conjugate base?

Back

A conjugate base is formed when a Bronsted-Lowry acid loses a proton (H⁺).

Front

According to the Arrhenius definition, what do acids produce in water?

Back

Acids produce H⁺ ions in water.

Front

What is the formula for titration involving acids and bases?

Back

The formula is MₐVₐ = MᵦVᵦ.

Front

What is another term for a base?

Back

Alkaline.

Front

What do H⁺ ions form when dissolved in water?

Back

What is a neutral solution?

Back

A neutral solution has a pH of 7.

Front

What is the relationship between pH and hydrogen ion concentration?

Back

pH is the negative logarithm of the hydrogen ion concentration: pH = -log[H⁺].
