Properties of water & Acids and Bases

Front

What is cohesion?

Back

Cohesion is the attraction between water molecules, causing them to stick together.

Front

Which pH level indicates a stronger acid?

Back

pH 1 is a stronger acid compared to pH 4, pH 8, and pH 13.

Front

What pH level do weaker bases have?

Back

Weaker bases have a pH closer to 8.

Front

What forces are responsible for capillary action?

Back

Capillary action is caused by adhesion, cohesion, and surface tension.

Front

What do acids produce when dissolved in water?

Back

Acids produce hydrogen ions when dissolved in water.

Front

Define adhesion in the context of water properties.

Back

Adhesion is the attraction between water molecules and other substances.

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.

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).

Front

What is a neutral pH level?

Back

A neutral pH level is 7, indicating a balance between hydrogen ions and hydroxide ions.

Front

What happens to pH when an acid is added to water?

Back

The pH decreases, indicating an increase in hydrogen ion concentration.
