Redox, Acid-Base, and Precipitation Reaction

Front

What does the (s) mean in a chemical equation?

Back

(s) indicates that the substance is a solid or precipitate that does not dissolve in water.

Front

What ions do acids release in water?

Back

Acids release H+ ions in water.

Front

What ions do bases release in water?

Back

Bases release OH- ions in water.

Front

What is a redox reaction?

Back

A redox reaction is a chemical reaction involving the transfer of electrons between two species, resulting in changes in oxidation states.

Front

Define oxidation in terms of electron transfer.

Back

Oxidation is the process of losing electrons during a chemical reaction.

Front

Define reduction in terms of electron transfer.

Back

Reduction is the process of gaining electrons during a chemical reaction.

Front

What is a precipitation reaction?

Back

A precipitation reaction occurs when two aqueous solutions react to form an insoluble solid, known as a precipitate.

Front

What is the general form of a precipitation reaction?

Back

The general form is: A(aq) + B(aq) → AB(s), where AB is the precipitate.

Front

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

Back

Indicators are substances that change color at a specific pH level, helping to determine the acidity or basicity of a solution.

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.
