Approximations
Posted: Sun Dec 10, 2017 10:47 pm
Just for clarification, every time we use approximations, like in terms of determining pH, we have to justify it right?
Hi, HanSitoy,
If Keq is very small, it is obvious why you are using the approximation (it would still be a good idea to mention it in your solution). However, if it is not very small, you should always justify it by using 5% rule at the end.
