The product of molar concentration of `H_^+` and `OH^-` ions, the value of `K_w` at `25^oC` is _______

What is the concentration of H_3O^+ and OH^- ions in water at 298 K ?

The product of molar concentration of hydrogen ions and hydroxide ions in a 0.01 M aqueous solution of sodium chloride is known as

The solution with the lowest concentration of H^(+) ion is

Assertion : The equilibrium constant for the reaction CaSO_(4).5H_(2)O(s)hArrCaSO_(4).3H_(2)O(s) + 2H_(2)O(g) is K_(C) = ([CaSO_(4).3H_(2)O][H_(2)O]^(2))/([CaSO_(4).5H_(2)O]) Reason : Equalibrium constant is the ration of the product of molar concentration of the substance produced to the product of the molar concentrations of reactants with each concentrations term raised to the power equal to the respective stoichiometric constant.
