How do you find KA and KB values?
Furthermore, how do you find KB from Ka?
Solve the equation for Kb by dividing the Kw by the Ka. You then obtain the equation Kb = Kw / Ka. Put the values from the problem into the equation. For example, for the chloride ion, Kb = 1.0 x 10^-14 / 1.0 x 10^6.
Also Know, what is the kb value? Kb value refers to a standardized ASTM test that measures the relative strength of a non-aqueous cleaning fluid. Mild solvents with lower Kb values will may not be strong enough to dissolve ionics and fluxes.
Simply so, how do you find the Ka value?
Note that x is Related to pH and Calculate Ka As noted above, [H3O+] = 10-pH. Since x = [H3O+] and you know the pH of the solution, you can write x = 10-2.4. It is now possible to find a numerical value for Ka. Ka = (10-2.4)2 /(0.9 - 10-2.4) = 1.8 x 10-5.
What is the difference between KB and Ka?
Ka is the "acid dissociation constant." It deals with the concentration of H + ions. Kb is the "base dissociation constant." It deals with the concentration of OH - ions.
