What would be the direction of flow of water through a semi-permeable membrane separating a 0.200 M solution of KCl and a 0.100 M solution of Mg(NO₃)₂ ? Explain your reasoning.

Expert Solution

KCl (aq.) ---------> K+ (aq.) + Cl- (aq.)

0.200 0.200 0.200 M

Total concentration of particles in the solution = 0.200 + 0.200 = 0.400 M

Mg(NO3)2 (aq.) ----------> Mg2+ (aq.) + 2 NO3- (aq.)

0.100 0.100 2(0.100)

Total concentration of particles in the solution = 0.100 + 2 (0.100) = 0.300 M

So, overall concentraion of solute particles in KCl is more than that of in Mg(NO3)2 .

Solvent will always flow from low concentrated solution to high concentrated solution. And hence water flow from Mg(NO3)2 solution to Kl solution.

An asymmetric ultrafiltration membrane is used with the aim of separating dyes from a liquid stream and to achieve a more concentrated dye-water mixture. The feed waste stream arrives at a flow rate of 2.2m3.hour-1 with concentration of 1.2 kg.m-3. The membrane’s operating characteristic was calculated from various experiments: where the bulk concentration C has units of kg.m-3 and flux is measured in m3.hour-1.m-2. If two membrane modules, each of area 25 m2, are simply placed in series, give reasonable...

An asymmetric ultrafiltration membrane is used with the aim of separating dyes from a liquid stream and to achieve a more concentrated dye-water mixture. The feed waste stream arrives at a flow rate of 3.0m3.hour-1 with concentration of 0.5 kg.m-3. The aim is to achieve a dye-water concentration leaving the membrane of 20 kg.m-3, so that it can be reused to dye fabric.

1) One method of producing drinkable water is to force seawater through a membrane that does not allow the salt to pass through. Such a process is called reverse osmosis (RO) and the membrane a reverse osmosis membrane. A large reverse osmosis facility continuously filters 2300 L of seawater per hour. The seawater contains sodium chloride (NaCl) at a concentration of 1.4 M. Two streams emerge from the RO facility: (1) a “brine” stream with a sodium chloride concentration of...
