Question

Give any three property of acids with examples

Answer 1

Answer:

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

2)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.

3)Acids react with active metals to yield hydrogen gas. Recall that an activity series is a list of metals in descending order of reactivity. Metals that are above hydrogen in the activity series will replace the hydrogen from an acid in a single-replacement reaction, as shown below:

Zn(s)+H2SO4(aq)→ZnSO4(aq)+H2(g
