Strong and weak acids

What is a solution with pH lower than 6 called?

• Alkaline

• Neutral

• Acidic

• Basic

Which solution would likely have a lower pH, Solution A or Solution B? (Red particles are H+ and OH- particles are blue)

• Solution A

• Solution B

• Both have the same pH

• Neither, pH cannot be determined

What type of solution is Solution D based on the presence of blue particles? (Red particles are H+ and OH- particles are blue)

• Acid

• Neutral

• Alkali

• Salt

Which solution is likely to have a higher pH, Solution C or Solution D? (Red particles are H+ and OH- particles are blue)

• Solution C

• Solution D

• Both have the same pH

• Cannot be determined

What is the degree of dissociation in a dilute strong acid?

• Low degree

• High degree

• No dissociation

• Medium degree

What is formed when particles in a strong acid dissociate?

• Molecules

• Atoms

• Ions

• Compounds

If a solution has a high concentration of H⁺ ions, what can be said about its pH?

• High pH

• Low pH

• Neutral pH

• pH of 7

In which solution is the concentration of H⁺ ions higher: stomach acid or vinegar?

• Stomach acid

• Vinegar

• Both are equal

• Neither

Choose the definition of a strong acid

• An acid that only reacts with bases.
• An acid that completely dissociates in solution.
• An acid that does not dissociate in solution.
• An acid that partially dissociates in solution.

Choose the definition of a weak acid

• An acid that completely dissociates in solution.
• A base that partially dissociates in solution.
• An acid that partially dissociates in solution.
• A neutral substance that does not affect pH.
