WebBased on proportions, I estimated 1.749E-9 M C, 7.35E-5 M B, and 3.086E-3 M A at equilibrium. I plug these all into the ionic strength equation and I get a value of 3.168E-3 M, versus 3.162E-3 for a monoprotic acid of same pH. So, very little difference. Now, how awful were those assumptions?? Go ahead and laugh, I can take it. More WebAs the ionic strength increases, an ion loses some of its effectiveness, and its activity coefficient decreases. As ... This equation is referred to as the Debye-hückel Limiting Law (DhLL). In solutions of very low ionic strength (µ < 0.01 M), the DhLL can be used
