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

How many amps does a kW heater at 240 volts take?

There is one part of the question missing. To find an answer the kW of the heater must be stated. Then the equations used are, to change kW to watts, Kw/1000 = watts. Once that is found then use, I = W/E, Amps = Watts/Volts. This will give you the value in amperage of the heater.

What is the pH of pure water at 313 K if Kw at that temperature is 2.917 x 10 -14?

"The pH of PURE water will always be 7." This is false. As the temperature rises for pure water, so does the Kw value. Kw=2.917 x 10^-14. Kw=[OH-][H+]. Kw=[1.708 x 10^-7]^2. -log(1.708 x 10^-7)=6.76=pH
