Unit 11 BR #5: Acid Base Theory and Calculations

Front

What is the formula to calculate the concentration after dilution?

Back

C1V1 = C2V2, where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.

Front

What is the resulting concentration if you dilute 250.0mL of 0.0366M KMnO4 solution with water to a total volume of 2000mL?

Back

0.004575M

Front

According to Arrhenius acid-base theory, what is an acid?

Back

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

Front

What is an Arrhenius base?

Back

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

Front

What volume of 0.50M CuSO4 solution is needed to prepare 100.0mL of 0.15M CuSO4 solution?

Back

30.0mL

Front

What is the definition of an Arrhenius acid?

Back

An Arrhenius acid is a substance that increases the concentration of H+ ions in aqueous solution.

Front

What is the definition of an Arrhenius base?

Back

An Arrhenius base is a substance that increases the concentration of OH- ions in aqueous solution.

Front

What happens to the pH of a solution when an acid is added?

Back

The pH of the solution decreases.

Front

What happens to the pH of a solution when a base is added?

Back

The pH of the solution increases.

Front

What is the relationship between pH and H+ concentration?

Back

pH = -log[H+], where [H+] is the concentration of hydrogen ions.
