Question

1. acid has the same ph as... (a) acidic (b) neutral (c) ph (d) basic 9) predict the ph of liquid drain cleaner, which is a very strong base. (a) 0 (b) 5 (c) 9 (d) 14 10) what type of reaction occurs when an acid and a base are mixed? (a) base reduction (b) combustion (c) oxidation (d) neutralization 11) which substance would most neutralize an acid food? (a) water with a ph value of 8.7 (b) dairy with a ph value of 5.2 (c) citrus with a ph value of 2 - 3 (d) baking soda with a ph value of 8 - 9

Explanation:

1. An acid has a sour taste. Bases are bitter - tasting and soapy to the touch. Neutral substances have neither acidic nor basic properties and pH is a measure of acidity or basicity. So the answer to the first question is related to the taste property of acids.
2. The pH scale ranges from 0 - 14. Acids have pH values less than 7, neutral substances have a pH of 7, and bases have pH values greater than 7. A very strong base has a high pH value close to 14.
3. When an acid and a base react, they form a salt and water in a neutralization reaction.
4. To neutralize an acid food, we need a base. Bases have pH values greater than 7. Among the options, baking soda with a pH value of 8 - 9 is a base.

Answer:

1. A. acidic
2. D. 14
3. D. neutralization
4. D. baking soda with a pH value of 8 - 9
