What is the ion-product constant for water?
The ionic product for water is defined byKW = [H3O+][OH-]For water at standard temperature and pressure, it is 1.00 x 10-14 mol2/dm6pKW (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.
What is meant by ionic product of water?
H2O=H+ +OH- Ka=[H+][OH-]/[H2O] Ka[H2O]=[H+][OH-] [H2O]=Constant Ka=[H+][OH-]=Kw=1*10-14
What is the difference between Kc and Kw for water?
Kc is the constant for concentration and Kw is the constant for water. Kc[h20] = [OH-][H+] which becomes Kw= [OH-][H+]
Prove that Kw equals product of Ka and Kb for an acid-base pair in water?
dissociation of acid in water: A + H2O <-> A- + H3O+ with dissociation constant Ka = [A-][H3O+]/[A][H2O] = [A-][H3O+]/[A]. dissociation of base in water: B + H2O <-> HB+ + OH- with dissociation constant Kb = [HB+][OH-]/[B][H2O] = [HB+][OH-]/[B] dissociation of water in itself: 2H2O <-> H3O+ + OH- with dissociation constant Kw = [H3O+][OH-]/[H2O]^2 = [H3O+][OH-] where [H2O] has been ommitted because it is a pure liquid. substituting relations for Ka and Kb into Kw gives: Kw = [H3O+][OH-] = (Ka[A]/[A-])(Kb[B]/[HB+]) = KaKb where [A] = [HB+] and [B] = [A-].

What is the pH range in hot water?
Can be anything, there's no strong link between pH and temperature. -------------- When the temperature is increasing the pH of water is decreasing and the ionic product (Kw) is increasing; at 50 0C the pH of pure water is 6,43. See the link below for the theory and for a table of pH.
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 sum of pH and pOH in any solution?
ONLY in pure water at 25 0C :pH + pOH = 14.00
Why maximum demand rating is not expressed in kw?
maximum demand is measured in kva because current drawn is dependent on power factor for the same load and current drawn is calculated with kva
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 is the difference between Kc and Kw for water?
Kc is the constant for concentration and Kw is the constant for water. Kc[h20] = [OH-][H+] which becomes Kw= [OH-][H+]
What chemical system can Ksp be assigned?
Ksp or solubility product is meaured for aqueous solutions of salts, for acids is Ka , for bases is Kb and for water is Kw.
What is the gross national product of Afghanistan?

How many KW in 32amps?
There are zero kW in 32 amps. Watts are the product of amps times volts. Once you find the voltage of the system multiply it times 32 amps and then divide that answer by 1000. This will give you the answer in kW.
What is Kwatt?
A kW is a kilowatt. A way of measuring power. One kilowatt is equal to 1000 watts: 1kW = 1000W Kw is the ion product constant for water at 25°C which is 1.0x10^-14. (chemistry)
