Unit 11: Exit Ticket #4 Acid Base Theory

Front

What is the Arrhenius definition of an acid?

Back

An Arrhenius acid is a substance that produces H+ ions in water.

Front

What is the Arrhenius definition of a base?

Back

An Arrhenius base is a substance that produces OH- ions in water.

Front

What is the product of the reaction HCl + Mg(OH)2?

Back

The products are MgCl2 + H2O.

Front

What does NaOH represent in Arrhenius theory?

Back

NaOH is an Arrhenius base.

Front

If a solution is basic, which ion is more prevalent?

Back

OH- ions are more prevalent in a basic solution.

Front

What is the role of H+ ions in acid-base reactions?

Back

H+ ions are responsible for the acidic properties of a solution.

Front

What is the role of OH- ions in acid-base reactions?

Back

OH- ions are responsible for the basic properties of a solution.

Front

What happens when an Arrhenius acid reacts with an Arrhenius base?

Back

They undergo a neutralization reaction, producing water and a salt.

Front

What is a neutralization reaction?

Back

A neutralization reaction is a chemical reaction between an acid and a base that produces water and a salt.

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.
