Question

1. alkaline means the same thing as...

(a) acidic
(b) neutral
(c) ph
(d) basic

1. predict the ph of liquid drain cleaner, which is a very strong base.

(a) 0
(b) 5
(c) 9
(d) 14

1. what type of reaction occurs when an acid and a base are mixed?

(a) base reduction
(b) combustion
(c) oxidation
(d) neutralization

1. which substance would most neutralize an acidic food?

(a) water with a ph value of 6 - 7
(b) dairy with a ph value of 5 - 7
(c) citrus with a ph value of 2 - 3
(d) baking soda with a ph value of 8 - 9

Explanation:

• For question 8: Alkaline substances are basic. Acids are the opposite, neutral has a pH of 7, and pH is a measure.
• For question 9: The pH scale ranges from 0 - 14, with 14 being the most basic for a strong base like liquid drain cleaner.
• For question 10: When an acid and a base react, they form a salt and water in a neutralization reaction.
• For question 11: A basic substance will neutralize an acidic food. Baking soda with a pH of 8 - 9 is basic among the options.

Answer:

1. D. basic
2. D. 14
3. D. neutralization
4. D. baking soda with a pH value of 8 - 9 (assuming option D was baking soda as the description was cut off but based on context)
