EFFECTS OF PRESSURE ON SOLUBILITY

HENRY'S LAW IS USED TO DESCRIBE THE

RELATIONSHIP BETWEEN SOLUBILITY OF GASSES

AND PRESSURE:

SOLUBILITY = K X P

SOLUBILITY
OF A GAS PRESSURE

HENRY'S LAW
CONSTANT

THE HIGHER THE PRESSURE, THE GREATER THE

SOLUBILITY

PRESSURE IS INCREASED P S

HOW PRESSURE
GAS SOLUBILITY EXAMPLE INFLUENCES SOLUBILITY

WHEN A CAN OF SODA IS OPENED,
BUBBLES COME OUT FROM THE SODA

THIS OCCURS BECAUSE THE WHICH CAUSES THE
PRESSURE OF CO GAS IN THE GAS TO BECOME LESS AS THE TEMPERATURE IS DECREASED,
2
CAN DECREASES WHEN IT IS SOLUBLE THE GAS MOVES MORE SLOWLY, AND
OPENED
IS THUS LESS PRONE TO ESCAPING THE
P S SOLUTION. THEREFORE, ITS

SOLUBILITY IS HIGHER AT LOWER
