The product of concentrations of H1 and OH ions in water at a particular temperature is known as ionic product of water. The value of Kw increases with the increase of temperature, i.e., the concentration of H+ and OH- ions increases with increase in temperature. The value of Kw at 25degreeC is 1 x 10-14.

Ionic product of water isa)constant above boiling point of waterb)cons...
The ionic product of water, also known as the water dissociation constant or Kw, is a measure of the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in water. It is defined as the product of the concentrations of these ions in water at a particular temperature. The ionic product of water can be expressed by the equation:
Kw = [H+][OH-]
Where [H+] represents the concentration of hydrogen ions and [OH-] represents the concentration of hydroxide ions.
Constant at a Particular Temperature:
The correct answer is option B, which states that the ionic product of water is constant at a particular temperature. This means that at a given temperature, the product of the concentrations of hydrogen ions and hydroxide ions in water remains constant.
Explanation:
The ionic product of water is influenced by the self-ionization of water molecules. In pure water, a small fraction of water molecules naturally ionize into hydrogen ions and hydroxide ions:
H2O ⇌ H+ + OH-
The concentration of hydrogen ions and hydroxide ions in pure water is extremely small, but it can be measured. At 25 degrees Celsius, the concentration of hydrogen ions and hydroxide ions in pure water is approximately 1 x 10^-7 moles per liter. Therefore, at this temperature, the ionic product of water can be calculated as:
Kw = [H+][OH-] = (1 x 10^-7)(1 x 10^-7) = 1 x 10^-14
This value of 1 x 10^-14 is constant at 25 degrees Celsius and is known as the ionic product constant of water (Kw). It represents the equilibrium constant for the self-ionization reaction of water.
The ionic product of water can be affected by changes in temperature. As the temperature increases, the equilibrium constant Kw also changes. However, at any given temperature, the value of Kw remains constant.
Conclusion:
In summary, the ionic product of water is constant at a particular temperature. At 25 degrees Celsius, the ionic product constant of water is 1 x 10^-14, representing the equilibrium constant for the self-ionization of water. Changes in temperature can affect the value of Kw, but at any given temperature, Kw remains constant.
