The ionic product for water is defined by
KW = [H3O+][OH-]
For water at standard temperature and pressure, it is 1.00 x 10-14 mol2/dm6
pKW (which is equivalent to the pH) will be 7 at room temperature,
because it is the -log10 of KW, and -log10 of the square root of 1x10-14 is 7.

The ion product constant for water, Kw, is the product of the concentrations of hydrogen ions and hydroxide ions in water at a given temperature. At 25°C, Kw is equal to 1.0 x 10^-14.

What is the dissociation constant k of pure water?
The dissociation constant of pure water is 1.9E-5.
What does K subscript w mean?
Kw is called the water autoprotolysis constant or water autoionization constant
The acid dissociation constant for an acid dissolved in water is equal to the?
The acid dissociation constant (Ka) for an acid dissolved in water is the equilibrium constant for the dissociation reaction of the acid into its ion components in water. It represents the extent of the acid's ionization in water.
What is the effect of dielectric constant of water on the solubility of the ionic salt?
The dielectric constant of water affects the solubility of ionic salts by reducing the electrostatic forces between ions. A higher dielectric constant allows water to better surround and dissolve the ions, increasing solubility. Conversely, a lower dielectric constant reduces the solubility of ionic salts in water.
The acid dissociation constant for an acid dissolved in water is equal to?
The acid dissociation constant (Ka) for an acid dissolved in water is equal to the ratio of the concentration of the products (H+ and the conjugate base) over the concentration of the reactant (the acid). It represents the extent of dissociation of the acid in water.
What is the dissociation constant k of pure water?
The dissociation constant of pure water is 1.9E-5.
What does K subscript w mean?
Kw is called the water autoprotolysis constant or water autoionization 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.
What are the ratings and certificates for Constant Hot Water - 1923?
Constant Hot Water - 1923 is rated/received certificates of: UK:U
The acid dissociation constant for an acid dissolved in water is equal to the?
The acid dissociation constant (Ka) for an acid dissolved in water is the equilibrium constant for the dissociation reaction of the acid into its ion components in water. It represents the extent of the acid's ionization in water.
How does the amount of matter remain constant while being recycled through the water cycle?
because the water will evapor when it remains to it constant
What is The constant recycling of water from the earths surface?
the water cycle
What is the effect of dielectric constant of water on the solubility of the ionic salt?
The dielectric constant of water affects the solubility of ionic salts by reducing the electrostatic forces between ions. A higher dielectric constant allows water to better surround and dissolve the ions, increasing solubility. Conversely, a lower dielectric constant reduces the solubility of ionic salts in water.
Is water have specific heat at constant volume or not?
Yes it has! the specific heat of water at constant volume is given by cV : Heat capacity at constant volume cP : Heat capacity at constant pressure : Thermal expansion coefficient : Isothermal compressibility : Density
When you squeeze a bottle of water the water rises up what does the water represents?
A constant volume.
Does the total amount of water on earth remain fairly constant or change regularly?
fairly constant
An equilibrium constant for the dissolving of a sparingly soluble ionic compound in water...?
solubility product constant.
