Acids, Bases, and Water Properties Practice

Front

What property of water allows a paperclip to float on its surface?

Back

Surface tension is the property of water that allows a paperclip to float when gently placed on it.

Front

What is surface tension?

Back

Surface tension is the property of water in which water molecules at the surface tend to stick together.

Front

What does a pH of less than 7 indicate?

Back

A pH of less than 7 indicates that a solution is acidic.

Front

What does a pH of more than 7 indicate?

Back

A pH of more than 7 indicates that a solution is basic.

Front

What pH value is associated with weaker bases?

Back

Weaker bases have a pH closer to 8.

Front

What are the properties of acids as described by Boyle?

Back

Acids have a sour taste, are corrosive, and change litmus paper from blue to red.

Front

What is the pH range for neutral solutions?

Back

The pH range for neutral solutions is 7.

Front

What is the characteristic taste of acids?

Back

Acids typically have a sour taste.

Front

What happens to water molecules at the surface of water?

Back

Water molecules at the surface tend to stick together due to surface tension.

Front

What is the effect of acids on litmus paper?

Back

Acids change litmus paper from blue to red.
