Properties of Water, Acids, and Bases Practice Flashcard

Front

What is the pH scale?

Back

The pH scale measures how acidic or basic a solution is, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What are acids?

Back

Acids are substances that have a pH less than 7, taste sour, and can be corrosive.

Front

What are bases?

Back

Bases are substances that have a pH greater than 7, feel slippery, and can neutralize acids.

Front

What is adhesion in relation to water?

Back

Adhesion is the property of water that allows it to stick to other substances, such as the sides of a glass tube.

Front

What is cohesion in relation to water?

Back

Cohesion is the property of water that allows water molecules to stick to each other, contributing to surface tension.

What is the effect of acids on litmus paper?

Back

Acids turn blue litmus paper red.

Front

What is the effect of bases on litmus paper?

Back

Bases turn red litmus paper blue.

Front

What is a neutral solution?

Back

A neutral solution has a pH of 7, meaning it is neither acidic nor basic.

Front

What is an antacid?

Back

An antacid is a substance that neutralizes stomach acid, typically containing bases.

Front

What is surface tension?

Back

Surface tension is the cohesive force at the surface of a liquid that makes it behave like a stretched elastic membrane.
