acid base review

Front

What is an acid according to Arrhenius theory?

Back

An acid is a substance that increases the concentration of H⁺ ions in aqueous solution.

What is a base according to Arrhenius theory?

Back

A base is a substance that increases the concentration of OH^- ions in aqueous solution.

Front

What happens in a neutralization reaction?

Back

An acid reacts with a base to produce water and a salt.

Front

What is the pH scale?

Back

The pH scale measures the acidity or basicity of a solution, ranging from 0 (acidic) to 14 (basic), with 7 being neutral.

Front

What is the role of indicators in acid-base chemistry?

Back

Indicators are substances that change color in response to changes in pH, helping to identify whether a solution is acidic or basic.

Front

What is the difference between strong and weak acids?

Back

Strong acids completely dissociate in water, while weak acids only partially dissociate.

Front

What is the significance of hydronium ions (H₃O⁺) in acid-base reactions?

Back

Hydronium ions are formed when acids donate protons to water, increasing the acidity of the solution.

Front

What is the significance of hydroxide ions (OH^-) in acid-base reactions?

Back

Hydroxide ions are produced by bases and are responsible for the basicity of a solution.

Front

How do you calculate the molarity of a solution?

Back

Molarity (M) is calculated as the number of moles of solute divided by the volume of solution in liters.

Front

What is a conjugate acid-base pair?

Back

A conjugate acid-base pair consists of two species that differ by the presence or absence of a proton (H⁺).
