Water - Solubility - Ions
Solubility of Gases.
The solubility curve for gases is the opposite
of the solubility curve for solids.
The solubility of a gas decreases as the temperature increases.
The graph below shows the solubility curve for oxygen gas.
The temperature range shown is approximately 0 to 50 °C.
life such as snails and
depend on the amount of oxygen dissolved in water.
Some power stations use water as a coolant
and may return warm water into a river.
This makes the amount of dissolved oxygen in the river decrease.
Aquatic life will die if the oxygen level goes too low.
dioxide can be dissolved in
water under pressure
to produce carbonated water which is used in fizzy drinks.
The dissolved gas bubbles out of the water
when you open the bottle or can and release the pressure.
Some carbon dioxide dissolves naturally in water.
Chlorine can be dissolved in water to make bleach and kill bacteria.
