The properties of a good primary standard include the following except?
Take Free Practice Test On 2026 JAMB UTME, Post UTME, WAEC SSCE, GCE, NECO SSCE
Correct Answer: Option 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
