The properties of a good primary standard solution include the following except?
- High molecular mass
-
low molecular mass
- high degree of purity
- readily available
The correct answer is: B
Explanation
Properties of a good standard solution
- High purity.
- Stability (low reactivity)
- Low hygroscopicity (to minimize weight changes due to humidity)
- High equivalent weight (to minimize weighing errors)
- Non-toxicity.
- Ready and cheap availability.
- High molecular mass
