Question

List four general properties of acidic solutions.

1) dissolve active metals producing hydrogen gas
2) react with bases to form water and salts
3) taste bitter
4) taste sour
5) react with acids to form water and salts
6) cause litmus indicator dye to turn red
7) cause litmus indicator dye to turn blue
8) feel slippery on the skin

Answer 1

Acidic solutions are known for having a sour taste, reacting with active metals to produce hydrogen gas, changing the color of acid-base indicators (such as turning blue litmus paper red), and neutralizing bases to form water and salts.

Step-by-step explanation:

Acidic solutions exhibit several characteristic properties. Here are four general properties of acidic solutions:

• Acids have a sour taste. Common examples include the sharp taste of citric acid in lemons and acetic acid in vinegar.
• Acids react with active metals to produce hydrogen gas. This reaction occurs with metals that are above hydrogen in the activity series, where the metal displaces the hydrogen in a single replacement reaction.
• Acids cause certain acid-base indicators to change color. For instance, blue litmus paper turns red in an acidic environment, while phenolphthalein turns colorless.
• Neutralization reactions take place when acids react with bases, yielding water and salts.
