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
2)Why do we set our ICE Table resulting equation equal to Ka as opposed to Kb?In this problem for example... Find the Ph of a .20 solution of KCN, we do CN- + H20 <--> HCN + OH- . Why do we choose CN- instead of K and then set this equal to Kb? Logged AWK Retired ...
Oh nvm i found the answer to my own problem. HNO2 5.6 × 10−4 is the ka value of HNO2 my equation NO2 + H2O - - > HNO2 + OH^- therefore i need the Kb of NO2 so i do: Kw/Ka 1.0E-14/5.6E-4 = ans 1 square root of (ans1 * 0.22) = 1.98208...E-6 ...

To learn more about acids and bases, review the accompany lesson on How to Calculate the Ka or Kb of a Solution. This lesson covers the following objectives: Understanding acids and bases at a molecular level Using an equation to determine how well an acid or base dissociates ...
It’s true, I draw on experiences that reach back to the dark days of mainframes and dumb terminals, but I don’t count that as any special talent for “reviewing.” I also have the luxury of working with free software, and removing the money element from the equation changes things ...
A compound is acidic if it can donate hydrogen ions to an aqueous solution, which is equivalent to saying the compound is capable of creating hydronium ions (H30+). The general equation describing what happens to an acid (HA) in solution is: ...
or base and its "conjugate" base or acid, respectively. To determine a buffer's pH--or extrapolate from its pH the concentration of any one of its components--you can make a series of calculations based on the Henderson-Hasselbalch equation, which is also known as the "buffer equation."...
Carleman estimates for the one-dimensional heat equation with a discontinuous coefficient and applications to controllability and an inverse problem We study the observability and some of its consequences (controllability, identification of diffusion coefficients) for one-dimensional heat equations with... ...
4a and b). The Ashenge glass shards are peralkaline (Equation (1)) (Le Bas et al., 1986). AST-1; 2; 5; and 7 are further classified as comendites (Al2O3 > 1.33(FeOT + 4)) (Le Maitre, 2002) whereas other Ashenge tephras are pantellerites (Al2O3 < 1.33(FeOT + 4))....
