Keonine 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

What is an acid?

Back

An acid is a substance that donates protons (H+) in a chemical reaction.

Front

What is a base?

Back

A base is a substance that accepts protons (H+) or releases hydroxide ions (OH-) in 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 spectator ions in a reaction?

Back

Spectator ions are ions that do not participate in the actual chemical reaction and remain unchanged.

Front

How can you identify a precipitate in a reaction?

Back

A precipitate can be identified by observing the formation of a solid that settles out of the solution.
