Strong acids, for which K, is very large,...
1)Calculate the percent ionization of a 0.330 M solution of hypochlorous acid. % Ionization = % 2)In the laboratory a student measures the percent ionization of a 0.405 M solution of hydrofluoric acid to be 4.35 %. Calculate value of Ka from this experimental data. Ka = 3)The hydroxide ion concentration of an aqueous solution of 0.405 M nitrous acid is [OH-] = M. 4)The pOH of an aqueous solution of 0.405 M hydrofluoric acid is
What is the hydronium ion concentration, pH, and percent ionization of a .025M solution of carbonic acid? Ka = 4.5 x 10^-7
- Given this concentration n ratio what is the pH (show work),
Ka and percent ionization of this species
( HA+H2O← → A- + H3O+ , acid. Initial concentration: 0.01
mol/L)
HA: 9.77x10^-3 mol/L
H2O: 55.6 mol/L
A- : 2.34x10^-4 mol/L
H3O+: 2.34x10^-4 mol/L
- Also if we increase the initial concentration how does this
affect the ph n the Ka such as increasing it to .1mol/L
- is you have initial concentration of .001 if u increase
strength what...
