At a constant 100 C and 1 ATM ambient pressure, I believe it should be 1 as the gaseous and liquid phases would be equally favored. This is due to the fact that the vapor pressure of liquid water at 100 C is 1 ATM.

What is the difference between Kc and Kw for water?
Kc is the constant for concentration and Kw is the constant for water. Kc[h20] = [OH-][H+] which becomes Kw= [OH-][H+]
What does K subscript w mean?
Kw is called the water autoprotolysis constant or water autoionization constant
What information does an acid or base equilibrium constant give?
The information an acid or base equilibrium constant gives is that the acidity and base levels are equal to the equilibrium constant multi[plied by the water concentration.
What is ion product constant?
Ion product constant is essentially when something reaches equilibrium. Such as in the case of water. When water reaches its ion product constant it becomes both a base and an acid, reaching equilibrium.
What is the value for the ionization constant Kw for water at 25 degrees celsius?
1.0*10^-14 No Units
How is Kw valid?
Kw is the ionisation constant for water at 25°C which value is 1.0x10^-14. (chemistry)In water at any pH the equilibrium state Kw is defined by and equal to the 'ion product':Kw = [H3O+]*[OH-] = 1.0*10-14at room temperature 25°C

Why kw of water remains same when small amount of acid or base is added?
Yes, it is an equilibrium constant, ONLY depending on the kind of reaction (Kw for water protolysis) and on temperature (according to Arrhenius) and never, NEVER on concentrations of its reactants and products:that is just why it is called a 'C O N S T A N T'
An equilibrium constant for the dissolving of a sparingly soluble ionic compound in water...?
solubility product constant.
The abbreviation Kw represents the what?
The ionization constant of water at 250C, its value is 1x10-14 A: ion-product constant of water.
How are the concentrations of hydrogen ions and hydroxide ions related in an aqueous solution.?
If their concentrations are multiplied with one other the product equals the water constant Kw:a kind of 'equilibrium constant' of the 'water equilibrium' reactions and vice verse: *)[H+]*[OH-] = Kw = 1.0*10-14or in negative log10 value's: (analogs of pH = -log[H+] ) pH + pOH = pKw = 14.0*) This equilibrium state is reached very quickly, so in any watery solution this is always a constant value. [H+] and [OH-] are always depending on each other: If you add acid (H+) then H+ goes up AND SO OH- goes down!H+ + OH- H2O
Does taking water out of an equilibrium reaction change the equilibrium constant?
No, the equilibrium constant is independent of concentration as long as the ratio of products and reactants remains as is. It can be effected by anything that would influence the ratio of products and reactants, such as changes in temperature or the addition of a catalysis.
What is the value for the ionization constant Kw for water at 25 degrees celsius?
1.0*10^-14 No Units
What are Kp aND KC?
Kc is the equilibrium constant of a chemical reaction; Kp is the equilibrium constant of a chemical reaction at constant pressure.
