Can someone explain this?

“Removing water from H3PO4 (aq) + H2O (l) ⇌ H3O+ (aq) + H2PO4− (aq): Reaction shifts left. All concentrations would increase proportionately; because there are more products than reactants (and the stoichiometric coefficient is 1 for each reactant and product), the value of Q will increase.”

It's not clear why removing water would cause the concentrations of all the other species to increase. I'm sure I'm overlooking something elementary.

Concentration = moles/L. If you decrease water (decrease L), your concentration would increase.

That was elementary! Thanks!
