SPS6- Solutions, Solubility Curves & Acids/Bases

Front

What is a solution?

Back

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

Front

What is solubility?

Back

Solubility is the ability of a substance (solute) to dissolve in a solvent at a given temperature and pressure.

Front

What does it mean if a solution is saturated?

Back

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

Front

What is an unsaturated solution?

Back

An unsaturated solution is one that can still dissolve more solute at a given temperature and pressure.

Front

What is a concentrated solution?

Back

A concentrated solution has a large amount of solute relative to the amount of solvent.

Front

What is a dilute solution?

Back

A dilute solution has a small amount of solute relative to the amount of solvent.

Front

What happens when an acid is added to water?

Back

When an acid is added to water, it dissociates into ions, increasing the concentration of hydrogen ions (H+) in the solution.

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), with 7 being neutral.

Front

What does blue litmus paper indicate?

Back

Blue litmus paper turns red in acidic solutions and remains blue in basic solutions.

Front

What does red litmus paper indicate?

Back

Red litmus paper turns blue in basic solutions and remains red in acidic solutions.
