The movement of a solvent through a membrane separating two solutions of different concentrations. The solvent from the side of weaker concentration usually moves to the side of the stronger concentration, diluting it, until the concentrations of the solutions are equal on both sides of the membrane.
We manage Trafalgar Square, one of Londonâs most vibrant spaces in the middle of the city. Find out about the history of this heritage site, its statues and its fountains.
The square is where routes from all four directions meet: in the west, there is a workshop and the House of the Queen of the Night, to the south lies New Narakort square with its inn, and to the east the town hall, past which the Merchants' Gate is visible. The route north is barricaded and blocked.
