OSMOSIS AND DIFFUSION FOR MY TUITION STUDENTS

FACT 1:

STRONG SOLUTION = HYPERTONIC SOLUTION = CONCENTRATED SOLUTION

CONTAINS LESS FREE WATER MOLECULES

THEREFORE : LOW WATER POTENTIAL

FACT 2:

WEAK SOLUTION = HYPOTONIC SOLUTION = DILUTE SOLUTION

CONTAINS MORE FREE WATER MOLECULES

THEREFORE: HIGH WATER POTENTIAL

FACT 3:

WATER ALWAYS HAS THE HIGHEST WATER POTENTIAL

FACT 4:

OSMOSIS: MOVEMENT OF WATER MOLECULES FROM SOLUTION WITH HIGH WATER POTENTIAL (DILUTE SOLUTION) TO SOLUTION WITH LOW WATER POTENTIAL (CONCENTRATED SOLUTION) ACROSS A SEMI PERMEABLE MEMBRANE
