Nov 13, 2015 at 21:40 | comment | added | DavePhD | @Shadock right, it can't just be approximated as water, so you need to use activity instead of concentration. See the references in my answer and also pubs.acs.org/doi/abs/10.1021/ac60302a030 for more information | |
Nov 13, 2015 at 21:20 | comment | added | ParaH2 | @DavePhD yeah you right i will erase my comment. But I'm not sure like you said that in HCl 5M, HCl is almost 100% dissociated. Because we are speaking about dissolution of HCl in a mixture of HCl and water which can't be approximate at just water here. My knowledge in dissolution is not really important but I have some doubts. If you know some good lectures please tell me. Friendly :) | |
Nov 13, 2015 at 19:50 | comment | added | DavePhD | @Shadock if the dissociation constant were really only 1, at 5M, the HCl would only be about 36% dissociated, but because the dissociation constant is more like 1000000, HCl is almost 100% dissociated in 5M HCl | |

Apr 11, 2015 at 16:08 | comment | added | Andy | It's because HCl is so strong in aqueous solution. In certain other solvents, you may need to actually calculate it. Also, note that in especially high concentrations you may need to consider the activity rather than just plugging in concentration | |
