  What determines the speed of water flow from a hyposomatic to a hypersomatic solution. For instance, if I had a concentrated Nacl solution would water flow faster to it or to a concentrated MgBr, NaBr, MgCl, AgCl, etc. solution?
  Is it solely a function of concentration or does the dissociation constant of the salt have something to do with it?

  It’s been a while since I’ve studied this, but I do remember the method.
  You need to use a formula you’ve seen, and calculate what the ‘concentration gradient’ is.
  NaCl whill ‘fall apart’ into Na+ en Cl- in water,
  whereass e.g. MgCl2 will form Mg2+ and 2 Cl-
  Since MgCl2 will form more atoms it’ll have a higher concentration-gradiënt and the water will flow to the MgCl2 to compensate for the difference.
  You need a formula to calculate the exact figures here, but if I remember correctly, that’s bassicly al there is to it.

  the factors affecting the velocity should be- mass of ion , no. of ion produced per molec. and in bulk, [as said above] n temp. which relates to KE…
  am too. curious abt the formula///

  Does the ration of postive to negative ions have anything to do with it? For instance if I had Na2So4 then I would have 2 Na+ and one SO4-. But if I had MgCl2 then I would have 2 anions and one cations.
  So does water flow faster toward a solution with more positive ions (na2so4) or a solution with more negative ions (mgcl2)?
