Find the percent ionization of a 0.200M acetic acid solution if it’s pKa=4.74
- 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...
