Acids and Bases

Front

What is an Arrhenius acid?

Back

An Arrhenius acid is a substance that produces hydrogen ions (H⁺) in a solution.

Front

What is the pH range of bases?

Back

Bases have a pH greater than 7.

Front

What components make up an oxyacid?

Back

An oxyacid is made up of hydrogen, oxygen, and another element.

Front

Which of the following are Arrhenius acids: H₂C₂H₃O₂ and H₃PO₄ or NaSCN and Na₂S₂O?

Back

H₂C₂H₃O₂ and H₃PO₄ are Arrhenius acids.

Front

What ions do Arrhenius acids create in solution?

Back

Arrhenius acids create hydronium ions (H₃O⁺) in solution.

Front

What is a base according to the Arrhenius definition?

Back

A base is a substance that produces hydroxide ions (OH⁻) in a solution.

Front

What is the general formula for an acid?

Back

The general formula for an acid is HA, where H is hydrogen and A is an anion.

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.

Front

What is the role of a proton donor in acid-base reactions?

Back

A proton donor is a substance that donates a hydrogen ion (H⁺) to another substance.

Front

What is the significance of the pH scale?

Back

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