SPS6. Solutions, Acids, and Bases

Front

What is a solution?

Back

A solution is a homogeneous mixture 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 conductivity in the context of solutions?

Back

Conductivity is the ability of a solution to conduct electricity, which depends on the presence of ions in the solution.

Front

What is the role of H+ ions in acids?

Back

H+ ions are responsible for the acidic properties of a solution, and their concentration determines the pH level.

Front

What is the pH scale?

Back

The pH scale measures the acidity or basicity of a solution, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What happens to ionic compounds in water?

Back

Ionic compounds dissociate into their constituent ions when dissolved in water, allowing them to conduct electricity.

Front

How does temperature affect the solubility of solid solutes?

Back

Generally, higher temperatures increase the solubility of most solid solutes in a solvent.

Front

What is concentration?

Back

Concentration is the amount of solute present in a given volume of solvent, often expressed in molarity (moles per liter).

Front

What is the effect of temperature on the rate of solute dissolution?

Back

Increasing the temperature typically increases the rate at which solutes dissolve in a solvent.

Front

What is an acid-base indicator?

Back

An acid-base indicator is a substance that changes color in response to the pH of a solution, helping to determine its acidity or basicity.
