Ka to pKa - The acidity constant Ka is the equilibrium constant for dissociation of an acid into its conjugate base and H+. Ka is the acid dissociation constant. pKa is simply the -log of this constant. Similarly, Kb is the base dissociation constant, wh
The higher the Ka and Kb values, the weaker the acid or base. When Ka values equal Kb values, the acid is strong. Ka and Kb values do not provide information about acid and base strength. Create your account to access this entire worksheet ...
I understand the formula and how it works. My teacher told me a method of finding Ka or Kb. It was to say that b/c one of the concentrations is so small. You can considered it negligible. For instance. Kb = x^2/0.67- x= 2.5E-7 ...

I'm somewhat confused: in which case do you use ke/kb to find the ka of a base's conjuguate acid, and when can you use 1/kb? I mean, as far as I understand it, and acid reaction can be written like this: HA + H2O -> A- + H3O+ ...
For as many times as I’ve introduced old laptops on this blog, you’d think I’d have a formula or a template page tucked away somewhere. But I don’t, and here we are again with another underdog to report. I hope it’s not too dull for you; if it’s any consolation, I hav...
Typical household vinegar is a 0.9 M solution with a pH of 2.4. Using the data, it's possible to calculate the dissociation constant: Acetic Acid (CH3CO2)H) Hydronium Ions (H3O+) Acetate Ions ( CH3CO2-) Initial 0.9 M 0 0 Change -x M +x M +x M ...

In chemistry, a "buffer" is a solution you add to another solution in order to balance its pH, its relative acidity or its alkalinity. You make a buffer using a "weak" acid or base and its "conjugate" base or acid, respectively. To determine a buffer's p
Therefore, the coupling waveguide wall thickness has to be increasingly thin as the frequency increases, the design formula of the TE21-mode coupler is still applicable at the high-frequency region, if the waveguide wall thickness h < 0.05λ and the bandwidth is relatively narrow [17]....
