solubility,concentration,acids and bases

Which pH value indicates the most basic solution?

• 7

• 8

• 3

• 11

Which is the most likely pH for a solution of a weak acid?

• 1

• 5

• 11

• 14

If a solution is acidic, it can be neutralized by adding

• a stronger acid

• heat

• a base

• a weaker acid

When the pH of a solution becomes more basic, the number on the pH scale

• decreases

• increases

• stays the same

• triples

What base has a pH of 8.5?

• Blood

• Soap

• Baking Soda

• Drain Cleaner

Lemons would be classified as a

• Strong base

• Weak Base

• Strong Acid

• Weak Acid

Marti took a balloon and filled it with 14 grams of baking soda. She then put 40 mL of vinegar into an empty water bottle. Marti stretched the balloon onto the top of the bottle and recorded the mass. She then flipped the balloon up so the baking soda fell into the vinegar. She observed it bubbling and could hear it fizzing. Marti laughed as the balloon filled with the carbon dioxide that was given off. After the reaction stopped, on the bottom of the bottle, Marti notices a white and clear substance. She remembers that she had learned that when you mix an acid (Vinegar) and a base (baking soda), you create

• acid and metal

• acid and base

• base and water

• salt and water
