Acids and Bases Review

What is a strong base?

• A base that completely dissociates in water, releasing all of its hydroxide ions.

• A base that partially dissociates in water, releasing some hydroxide ions.

• A base that does not dissociate in water at all.

• A base that reacts with acids to form salts and water.

What does the pH scale indicate?

• A measure of temperature

• An indicator that tells if a substance is an acid or base.

• A scale for measuring density

• A method for determining color intensity

What are the products of a neutralization reaction?

• Water (H2O) and Ionic Salt

• Carbon Dioxide (CO2) and Water (H2O)

• Hydrogen Gas (H2) and Ionic Salt

• Oxygen Gas (O2) and Ionic Compound

What is a strong acid?

• An acid that partially dissociates in water, releasing some of its hydrogen ions.

• An acid that completely dissociates in water, releasing all of its hydrogen ions.

• An acid that does not dissociate in water at all.

• An acid that only dissociates in concentrated solutions.

How does a catalyst speed up a reaction?

• By increasing the temperature of the reaction.

• By lowering the activation energy of the reaction.

• By providing additional reactants for the reaction.

• By changing the color of the reactants.

What is the pH range of bases?

• 0 to 7

• 7 to 14

• 4 to 10

• 1 to 6

What is the pH range of acids?

• 0 to 3

• 4 to 6

• 0 to 7

• 7 to 14

What is the formula for calculating pH?

• pH = -log[H+]

• pH = log[H+]

• pH = [H+]/10

• pH = 14 - pOH

What is a base?

• A type of chemical that forms solutions that taste bitter and feel slippery, often containing hydroxide ions.

• A substance that donates protons in a chemical reaction.

• A type of chemical that forms solutions that taste sour and feel sticky.

• A compound that increases the concentration of hydrogen ions in a solution.
