Ocean Chemistry and Properties of Water

Front

What is adhesion in the context of water?

Back

Adhesion is the attraction between water molecules and other substances, allowing water to stick to surfaces.

Front

What is the result of carbon dioxide combining with seawater?

Back

The combination of carbon dioxide and seawater forms carbonic acid.

Front

Which part of a water molecule has a slightly positive charge?

Back

The hydrogen end of the water molecule has a slightly positive charge.

Front

Why does water have no net charge but has slight charges in different parts of the molecule?

Back

Water has no net charge because the oxygen end is slightly negative and the hydrogen end is slightly positive.

Front

What type of bond holds two water molecules together?

Back

Hydrogen bonds hold two water molecules together.

Front

What is cohesion in relation to water?

Back

Cohesion is the attraction between water molecules, which allows them to stick to each other.

Front

What is the significance of water's polarity?

Back

Water's polarity allows it to dissolve many substances, making it a universal solvent.

Front

What is surface tension in water?

Back

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

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces against gravity, due to adhesion and cohesion.

Front

What is the pH of pure water?

Back

The pH of pure water is 7, which is considered neutral.
