Question

19. State three chemical properties of acids.

​

Answer 1

Explanation:

1. Aqueous solutions of acids are electrolytes, meaning that they conduct an electrical current.
2. Acids have a sour taste.
3. .Acids change the color of certain acid-base indicators.
4. .Acids react with active metals to yield hydrogen gas.

Answer 2

Answer:

1 Aqueous solutions of acids are electrolytes, meaning that they conduct electrical current. Some acids are strong electrolytes because they ionize completely in water, yielding a great many ions. Other acids are weak electrolytes that exist primarily in a non-ionized form when dissolved in water.

2 Acids have a sour taste. Lemons, vinegar, and sour candies all contain acids.

3 Acids change the color of certain acid-base indicates. Two common indicators are litmus and phenolphthalein. Blue litmus turns red in the presence of an acid, while phenolphthalein turns colorless.
