Properties of Water

Front

What is the pH Scale?

Back

A scale with values from 0 to 14 used to measure the concentration of H+ ions in a solution.

Front

What is a Base in terms of pH?

Back

A solution with a pH more than 7, indicating a high concentration of OH- ions.

Front

What is a Solvent?

Back

The dissolving substance in a solution.

Front

What is the melting point?

Back

The temperature at which a solid becomes a liquid.

Front

What charge does the oxygen atom in water have?

Back

The oxygen atom in water is slightly negative.

Front

What is a Solute?

Back

The substance that is dissolved in a solution.

Front

What is the boiling point?

Back

The temperature at which a liquid becomes a gas.

Front

What is a Hydrogen Bond?

Back

A weak bond between a hydrogen atom and an electronegative atom, crucial in water's properties.

Front

What is the difference between an Acid and a Base?

Back

An acid has a pH less than 7 and increases H+ concentration, while a base has a pH greater than 7 and increases OH- concentration.

Front

What is a Buffer?

Back

A solution that resists changes in pH when small amounts of acid or base are added.
