How do you determine the indicator constant?
[OH-]=[acidic medium]. kw /[basic medium]KOH At const temp and pressure Kw/KOH=const.=K1=[H+][In-]/[HIn] pk1 is generally termed as indicator const.
How many kw are in 1 mgw?
1000 kw
How much KW for Fridge?
About 0.1 kW for a kitchen fridge.
How many watts in a kw?
1000 watts
1663170 btu's equals how many kw?
487.3044 kW
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 does K subscript w mean?
Kw is called the water autoprotolysis constant or water autoionization constant
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
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 value for the ionization constant Kw for water at 25 degrees celsius?
1.0*10^-14 No Units
Why the pH scale is up too14?
Kw of water changes when temperature changes. Usually the temperatue is 298K , Kw is a constant:10exp-14, so when you test pH, the (H+) is less than 10exp-14.
How do you determine the indicator constant?
[OH-]=[acidic medium]. kw /[basic medium]KOH At const temp and pressure Kw/KOH=const.=K1=[H+][In-]/[HIn] pk1 is generally termed as indicator const.
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-].
Will a 2.5 kw solar system power a house using 2500 kwh?
Well, I have a 2.5 kw pvground mounted system, but I never imagined that it would `power my house'. Truth be told, I doubt that 2.5 kw will barely boil an electrickettle. The real benefit is the cumulative effect of the constant day time output of the panels.
What is breaker size for 62.19 KW 3 phase?
A breaker protects the wire size of the feeder that is connected to it. The amperage of the load must be found. Without a voltage stated the amperage from the wattage given can not be calculated. The equation for amperage when the kw is given is A = kW x 1000/1.73 x volts x pf. The pf constant to use is .9.
