Front

What is an acid?

Back

An acid is a substance that donates protons (H+) in a solution. Example: Hydrochloric acid (HCl).

Front

What is a base?

Back

A base is a substance that accepts protons (H+) or donates hydroxide ions (OH-) in a solution. Example: Sodium hydroxide (NaOH).

Front

What is the pH scale?

Back

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

Front

What type of reaction is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts with oxygen, producing heat and light. Example: CH4 + 2O2 -> 2H2O + CO2.

Front

What is Boyle's Law?

Back

Boyle's Law states that the pressure and volume of a gas are inversely related at constant temperature. As volume increases, pressure decreases.

Front

What happens to pH as H3O+ ion concentration increases?

Back

As the H3O+ ion concentration increases, the pH of the solution decreases, indicating increased acidity.

Front

What is a neutral solution?

Back

A neutral solution has a pH of 7, meaning it is neither acidic nor basic.

Front

What is the difference between a strong acid and a weak acid?

Back

A strong acid completely dissociates in solution, while a weak acid only partially dissociates. Example: HCl (strong) vs. CH3COOH (weak).

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product. Example: 2H2 + O2 -> 2H2O.

Front

What is a double replacement reaction?

Back

A double replacement reaction occurs when two compounds exchange ions to form two new compounds. Example: AB + CD -> AD + CB.
