To estimate the mass of lime required to precipitate magneisum from sea water. Concept introduction: Magnesium is an alkaline earth metal and is prsent in sea water. The magnesium present in sea water can be extracted by precipitating it with either CaO or Ca ( OH ) 2 . The pure metal from the salt obtained can be obtained by the process of electrolysis . N u m b e r o f m o l e s = M a s s M o l e c u l a r m a s s Mass = Number of moles × Molecular mass
Solution Summary: The author calculates the mass of lime that must be used to precipitate magneisum from sea water.
To estimate the mass of lime required to precipitate magneisum from sea water.

Interpretation Introduction
Interpretation:
To estimate the mass of product produced at anode and cathode on electrolysis of MgCl2 and also total number of Faradays of electricity used.
Concept introduction:
Magnesium is an alkaline earth metal and is prsent in sea water. The magnesium present in sea water can be extracted by precipitating it with either CaO or Ca(OH)2. The pure metal from the salt obtained can be obtained by the process of electrolysis.
The reduction happens at cathode
The oxidation happens at anode.

Mass=Numberofmoles×Molecularmass
The total number of Faradays of electricity used is calculated by the number of electrons involved in the reaction
(c)
Interpretation Introduction
Interpretation:
To estimate how many Joules are required per mole for the given industrial process
