Unit 7 Part 2

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. She then tipped the balloon up so the baking soda fell into the vinegar. She observed it bubbling and could hear it fizzing. After the reaction stopped, on the bottom of the bottle, Marti notices a white and a clear substance. She remembers that she had learned that when you mix an acid (vinegar) and a base (baking soda), you create -

• acid & metal

• Acid and Base

• Base and water

• Salt & Water

In a water solution, how do acids differ from bases?

• Acids from salts and bases do not

• Acids turn litmus paper blue and bases turn it red

• Acids from H+ ions and bases from OH- ions

• Bases from salts and acids do not

Lemons would be classified as

• Strong base

• Weak base

• Strong acid

• Strong base

What base has a pH of 8.5?

• Blood

• soap

• baking soda

• Drain cleaner

When an acid and a base are mixed, what is the reaction called?

• Neutralization

• Hyrdolyzed

• Hydro ionization

• A salt and water reaction

Which solution reacts with LiOH to produce a salt and water?

• KCl

• CaO

• NaOH

• H²SO⁴

What is the pH of a solution that results from the complete neutralization of an HCl solution with a KOH solution?

• 1

• 7

• 10

• 4

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

• Decreases

• Increases

• Stays the same

• Triples

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

• A stronger acid

• Heat

• A base

• A weaker acid

Which pair of elements form an iconic bond with each other? (metal & nonmetal)

• KCl

• ICl

• PCl

• HCl
