Osmotic pressure formula conflict

[Alliekat423]

The kaplan book as the osmotic pressure formula as:

Osmotic pressure=MRT

Destroyer has the formula as:

Osmotic pressure=MRTi where i = Van't Hoff factor (# of particles that will theoretically dissociate as infinite dilution)

Anyone know which one to use?

The i is used when u are dealing with ions dissolved. for example, NaCl has a total of 2 ions so i=2. hope it helped

destroyer is correct. you have to take the i into account. (you will see that kaplan places osmotic pressure under "colligative properties" which means you have to take i into account)

 

[levyusupov]

the destroyer equation is the correct one.
