    Hi,

    One does not usually refer to concentration of water as water is the solvent in nature, so one talks about the concentration of the substance dissolved in water, i.e. the concentration of the solute e.g. of Na+ or of glucose that is dissolved in water.

    Conceptually, the idea of "concentration of water" is effectively the same as water potential i.e. the greater the proportion a water in a solution (therefore the lesser the amount of solute in it), the greater the water potential. the greater the water potential, the more the net movement of water is from that compartment to one with lower water potential. The idea of "concentration of water" is just a way of understanding that water moves from higher water potential area to lower one in a manner similar to a solute moving down its concentration gradient.

    I hope this makes things a bit easier for you.
