my answer would be yes because, a concentration is the measure of how much of a given substance there is mixed with another substance, so aslong as the water is mixed with something elce you can measure the concentation of water right?
Borek said:Side effect of water concentration is that sometimes you will find pKw (water ionic product) given as 14 and sometimes as 15.7. First number is based on assumption that water concentration is constant and doesn't change, second one takes care of water concentrations adding it to reaction quotient.
