Question

identify 3 important acids and state their importance.
1.
2.
3.
questions:

1. how are bases different from an acid?

1. what is one of the most common bases?
2. which is stronger: drain cleaner or aqueous ammonia?

read the following questions and answer based on your knowledge of bases.

1. sulfuric acid is also known as (battery acid, stomach acid,

citric acid, or vinegar)

1. which of these is a common base? (orange juice, water,

ammonia, or milk of magnesia)

1. certain items can act as an indicator because they change

(color, size, shape, or taste)

1. explain why you should never use taste as a test for an acid, even though there are

many acids we eat and drink.

1. sometimes when rain falls, it mixes with the pollutants in the air. an acid is then formed.

why might this be harmful to the environment and objects around us?

1. what color will litmus paper be in an acid? (red or blue) a base? (red or blue)
2. what color will phenolphthalein be in an acid? (pink or clear) a base? (pink or clear)

Explanation:

• Sulfuric acid: Commonly used in batteries, so it's called battery acid.
• Milk of magnesia: A well - known base used for various purposes like antacid.
• Color change: Indicators work by changing color in the presence of acids or bases.
• Safety with acids: Many acids are harmful (not just the ones we consume in small, safe amounts in food/drink), so tasting random acids is dangerous.
• Acid rain damage: Acid rain can corrode metals (e.g., bridges), damage buildings (e.g., limestone structures), and harm plants and aquatic life.
• Litmus paper: Turns red in acid and blue in base.
• Phenolphthalein: Clear in acid and pink in base.

Answer:

1. battery acid
2. milk of magnesia
3. color
4. Many acids are harmful and can cause burns or poisoning. Just because some acids (like in food/drink) are safe to consume in small amounts doesn't mean all acids are.
5. Acid rain can corrode metals (e.g., bridges), damage buildings (e.g., limestone structures), and harm plants and aquatic life.
6. In an acid: red; In a base: blue
7. In an acid: clear; In a base: pink
