SPS6. Solutions, Acids, and Bases

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 type of solution is formed when 150 g of sucrose is stirred in 100 mL of water at 20°C?

Back

The solution is unsaturated, meaning it can still dissolve more solute.

Front

What does a solubility curve illustrate?

Back

A solubility curve illustrates the effect of temperature on the solubility of a substance.

Front

How does temperature affect the solubility of solids in liquids?

Back

Raising the temperature of the solvent generally increases the rate at which solids dissolve.

Front

What is the pH range of acids?

Back

Acids have a pH range of 0 to less than 7.

Front

What is the pH range of bases?

Back

Bases have a pH range of greater than 7 to 14.

Front

What happens to blue litmus paper when it comes in contact with an acid?

Back

Blue litmus paper turns red when it comes in contact with an acid.

Front

What happens to red litmus paper when it comes in contact with a base?

Back

Red litmus paper turns blue when it comes in contact with a base.

Front

What is a saturated solution?

Back

A saturated solution is one that has dissolved the maximum amount of solute at a given temperature.

Front

What is the difference between a solute and a solvent?

Back

A solute is the substance that is dissolved, while a solvent is the substance that does the dissolving.
