Question
FeCl3 and MgCl2 solution was prepared by
dissolving FeCl3 (AR) and MgCl2 (AR) in
distilled water. Secondly, under rapid stirring,
NaHCO3 powder was slowly added to the
above solution to the desired basicity (B = 1)
which had been proved to be the optimal B
for turbidity removal. Thirdly, Na2HPO4 (AR)
was added to the PFMC solution as a
stabilizer ([Na2HPO4]/([Fe] + [Mg]) = 0.08).
i. What the chemical equation of the
Synthesis.
ii How much weight need to put NaHCO3
above solution the desired basicity (B=1)
iii. How much weight need to put Na2HPO4
on PFMC solution refering ([N22HPO4]/([Fe] +
[Mg]) = 0.08)
