What is the relationship between H+ and OH- concentrations in a basic solution?

• In a basic solution, the concentration of H+ ions is greater than that of OH- ions.

• In a basic solution, the concentration of H+ ions is equal to that of OH- ions.

• In a basic solution, the concentration of OH- ions is greater than that of H+ ions.

• In a basic solution, the concentration of OH- ions is less than that of H+ ions.

What is the pH of a strong base like NaOH?

• 7

• 10

• 12

• 14

What is the relationship between H+ and OH- concentrations in an acidic solution?

• In an acidic solution, the concentration of H+ ions is greater than that of OH- ions.

• In an acidic solution, the concentration of H+ ions is equal to that of OH- ions.

• In an acidic solution, the concentration of H+ ions is less than that of OH- ions.

• In an acidic solution, the concentration of H+ ions is negligible compared to that of OH- ions.

What is the effect of dilution on the pH of a strong acid?

• Diluting a strong acid increases its concentration of H+ ions, which decreases the pH.

• Diluting a strong acid has no effect on its pH.

• Diluting a strong acid decreases its concentration of H+ ions, which can increase the pH towards neutral.

• Diluting a strong acid makes it a weak acid, which has a higher pH.

What is the pH of a neutral solution?

• 5

• 6

• 7

• 8

How can you determine if a solution is acidic or basic?

• By measuring its pH; below 7 is acidic, above 7 is basic.

• By tasting the solution to check for sourness.

• By observing the color of the solution.

• By checking the temperature of the solution.

What is the significance of a pH of 12?

• It indicates a neutral solution with a pH of 7.

• It indicates a strongly acidic solution with a high concentration of H+ ions.

• It indicates a strongly basic solution, with a high concentration of OH- ions.

• It indicates a slightly basic solution with a pH between 7 and 10.

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

• A strong acid partially dissociates in solution, while a weak acid completely dissociates.

• A strong acid completely dissociates in solution, while a weak acid only partially dissociates.

• Both strong and weak acids completely dissociate in solution.

• A strong acid has a higher pH than a weak acid.

What is an example of a strong base?

• Potassium chloride (KCl)

• Sodium hydroxide (NaOH)

• Calcium carbonate (CaCO3)

• Ammonium sulfate ((NH4)2SO4)

What is the role of water in a neutralization reaction?

• Water acts as a catalyst in the reaction.

• Water is produced as a byproduct when H+ ions from the acid react with OH- ions from the base.

• Water neutralizes the acid before the reaction occurs.

• Water increases the temperature of the reaction.
