Physical and Chemical Properties of Acids

Click on the flashcard to see the answer

What is a common physical property of acids in aqueous solutions?

They have a sour taste.

What happens to blue litmus paper when it is placed in an acidic solution?

Blue litmus paper turns red.

What is a common chemical property of acids?

Acids can react with metals to produce hydrogen gas.

What type of ions do acids release in water?

Acids release hydrogen ions (H+).

Describe the electrical conductivity of acidic solutions.

Acidic solutions conduct electricity because they contain ions.

How do acids react with bases?

Acids react with bases to form salt and water in a neutralization reaction.

What effect do acids have on phenolphthalein?

Acids turn phenolphthalein colorless.

What is a characteristic odor of vinegar, an organic acid?

Vinegar has a pungent, sour smell due to the presence of acetic acid.

How do concentrations of ions differ in dilute and concentrated acids?

Concentrated acids have a higher concentration of hydrogen ions than dilute acids.

Explain how acids can affect certain metals.

Acids can corrode certain metals by reacting with them to form metal salts and hydrogen gas.

Can acids change the color of universal indicator? If so, how?

Yes, acids usually change universal indicator to red, orange, or yellow, depending on their strength.

What is the pH range generally associated with acids?

Acids typically have a pH less than 7.

Describe what happens in a reaction between an acid and carbonate.

Acids react with carbonates to produce carbon dioxide, water, and a salt.

Why are acids considered electrolytes?

Because they release ions in solution, allowing them to conduct electricity.

Give an example of an organic acid.

Citric acid, found in citrus fruits, is an example of an organic acid.
