Understanding Polar and Non-Polar Molecules

What are the materials required for the experiment discussed in the video?

• Two jars, water, vinegar, and salt

• Two jars, vinegar, oil, and sugar

• Two jars, oil, sugar, and salt

• Two jars, water, oil, and salt

Why is water considered an excellent solvent?

• Because it is non-polar

• Because it has no charges

• Because it has both positive and negative charges

• Because it is a solid at room temperature

What characteristic of salt allows it to dissolve in water?

• It is non-polar

• It is a gas

• It is polar with positive and negative charges

• It is a metal

What is the main difference between polar and non-polar molecules?

• Neither have any charges

• Both have charges but in different amounts

• Non-polar molecules have charges, polar do not

• Polar molecules have charges, non-polar do not

Why do polar molecules like salt mix with water but not with oil?

• Because oil is also polar

• Because oil is non-polar

• Because water is non-polar

• Because salt is non-polar
