Study Notes
Evalues and iFactor
- Evalues questions require finding the iFactor first, as it's essential to solve the problem using the law.
- Even if the iFactor is not explicitly requested, it's still necessary to find it.
iFactor Formula
- iFactor of a substance is calculated using the formula: Sodium Chloride (NaCl) = 1.8 (constant values)
Mut of a Substance
- Mut of a substance is a given value in the question.
- Example: Mut of Sodium Chloride = 38.5
Calculating iFactor
- Steps to calculate iFactor:
- Find the dissociation rate of each ion.
- Find the remaining percentage of the compound that did not dissociate.
- Add the two values.
- Divide the result by 100.
