Osmotic pressure and Raoult's law co-relation?
Consider two compartments A and B joined. A contains pure water. B contains brine (dilute). Consider the Vant Hoff factor ($i$).
Obviously pressure over B is less than over A.
We also know that the ...

Can we determine apriori the volume of solvent in an electrolyte
Suppose I would like to create a one molar solution of NaCl in water. The molar concentration is defined as
$c_i=\frac{n_i}{V} $
$n_i=1$ in this case. I need to take 58.5 grams of NaCl (atomic ...
