Unit 6-Solutions

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution. In a mixture of sugar and water, water is the solvent.

Front

What is an acid?

Back

An acid is a substance that donates protons (H+) in a solution and typically has a sour taste, can change the color of indicators, and reacts with metals.

Front

What is the property of acids that distinguishes them from bases?

Back

Acids taste sour, while bases feel slippery.

Front

What happens when gas particles collide with the walls of a container?

Back

The collisions of gas particles with the walls of a closed container create gas pressure.

Front

What is the role of litmus paper in acid-base testing?

Back

Litmus paper is used to test the acidity or basicity of a solution; red litmus paper turns blue in basic solutions, while blue litmus paper turns red in acidic solutions.

Front

What is a solution?

Back

A solution is a homogeneous mixture composed of two or more substances, where one substance (the solute) is dissolved in another (the solvent).

Front

What is the difference between a solute and a solvent?

Back

A solute is the substance that is dissolved in a solution, while a solvent is the substance that dissolves the solute.

Front

What is the significance of carbon dioxide in soft drinks?

Back

Carbon dioxide is dissolved in soft drinks to create carbonation, which gives the drink its fizz.

Front

What is the effect of temperature on gas pressure?

Back

Increasing the temperature of a gas increases its pressure if the volume is constant, due to increased kinetic energy of the gas particles.

Front

What is an indicator in chemistry?

Back

An indicator is a substance that changes color in response to the acidity or basicity of a solution.
