Write down the equation for the the Ka, the Kb, and the Kw, which is Kw = (Ka)(Kb). Solve the equation for Kb by dividing the Kw by the Ka. You then obtain the equation Kb = Kw / Ka. Step 3 Put the values from the problem into the equation. For example, for the chloride ...
, the dissociation constant for water. to put it another way: 2h 2 o ⇌ h 3 o + + oh − ksp = [h 3 o + ][oh − ] = 1∗10 −14 we can use this equation to calculate the hydronium ion concentration if we know the hydroxide ion concentration. [h 3 o + ][oh −...

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))....
Calculate the change in pH when 2x10-3 mol of HNO3 is added to 0.100 L of a buffer solution that is 6x10-2 M in HF (Ka=1.8 x10-4) and 0.116 M in NaF. Buffers: The pH of a buffer solution can be ...
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 ...
