Fatima has been asked to prepare a solution of Mg(ClO4 )2 with
an accurately known
concentration. However, she discovers that each time she tries to
weigh the Mg(ClO4 )2 the
mass is slightly greater. Explain this observation.
Homework Answers
Magnesium Perchlorate [Mg(ClO4)2] is a strong hydrate compound.
A hydrate compound is one that readily absorb water from the air into their solid structure .
Now as long as magnesium Perchlorate is remained open in air it readily absorb water from the air and as a consequence the mass of the initial magnesium Perchlorate increases gradually.
One molecule of [Mg(ClO4)2] absorb 3 molecule of water. This is the reason for the increase in mass of magnesium Perchlorate in open air .
