Which would have the higher osmotic pressure: a 0.10 M solution of NaCl or a 0.10 M solution of KBr?

Question

anonymous · Answer

they will have the same osmotic pressure  since osmotic pressure = M R T,
    M is the molarity
    R=0.0821 L atm K-1 mol-1 is the gas constant
    T is the thermodynamic (absolute) temperature

jfraser · Answer

if you had a solution of NaCl and a solution of CaCl2, then the CaCl2 would have the higher osmotic pressure because of the # of ions that are produced, but since NaCl and KBr both dissociate into 2 ions, even the ion factor is the same.
