What will be state of water at -25 C?
At -25 Celsius, water will be a solid. Converting from Celsius to Fahrenheit, -25 C is -13 F.
Which is not a way to express the hydroxide and hydronicum ion concentrations in pure water at 25?
One way to express the hydroxide and hydronium ion concentrations in pure water at 25°C is through the equation Kw = [H3O+][OH-], where Kw is the ion product constant for water. The concentration of hydronium ions ([H3O+]) is equal to the concentration of hydroxide ions ([OH-]) at 25°C, which is 1.0 x 10^-7 mol/L.
What is the state of phenol at 25 C degrees?
Phenol is a solid at room temperature (25°C). It has a melting point of 40.5°C, so at 25°C, it would exist in a solid state.
What is ionic product of water at 25 C?
The ionic product of water (Kw) at 25°C is 1.0 x 10^-14 mol^2/L^2. This value represents the equilibrium constant for the autoionization of water into hydronium (H3O+) and hydroxide (OH-) ions.
H2O physical state at room temperature?
Water (H2O) is in a liquid state at room temperature (around 20-25°C).
What will be state of water at -25 C?

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
What is the density of PURE water in its liquid state?
At 25 degrees C the density of water is 1.0 g/mL. If the temperature of the water goes above 25 degrees C the density will drop. If the temperature of the water goes below 25 degrees C the density will rise.

What is the state of OXYGEN at 25 degrees C?
Pure oxygen is a gas at 25 C, regardless of the pressure.
Describe the relationship between hydronium and hydroxide ion concentrations in an aqueous solution?
The relationship between hydronium (H3O+) and hydroxide (OH-) ion concentrations in an aqueous solution is governed by the autoionization of water. In pure water at 25°C, the concentrations of H3O+ and OH- ions are equal at 1.0 x 10^-7 M each due to water molecules acting as both acids and bases. This relationship is represented by the equation [H3O+][OH-] = 1.0 x 10^-14 at 25°C.
What is the product of H3O ion and OH- ion concentration in water?
The product of the H3O+ ion concentration and the OH- ion concentration in water is always equal to the ion product of water, which is 1.0 x 10^-14 at 25°C. This relationship is described by the equation [H3O+][OH-] = 1.0 x 10^-14.
Ionic product of water?
The ionic product of water, Kw, is the product of the concentrations of hydrogen ions (H+) and hydroxide ions (OH-) in water at a given temperature. It is a constant value at a given temperature, typically 25°C, and has a value of 1.0 x 10^-14 in pure water. Kw = [H+][OH-].
