Both calcium sulfate and magnesium sulfate can form hydrates with water. Could white anhydrous CaSO4or MgSO4 be substituted for anhydrous CuSO4 in the determination of moisture experiment? Explain. Can Calcium or Magnesium Sulfate Substitute for Copper Sulfate in Moisture Determination Experiments?

Can Calcium or Magnesium Sulfate Substitute for Copper Sulfate in Moisture Dedication Experiments?

The dedication of moisture content material in a pattern requires correct and dependable outcomes, which is why anhydrous copper sulfate (CuSO4) is used as an analytical reagent for this course of. CuSO4 is an efficient desiccant – it absorbs water from the pattern, forming anhydrous CuSO4 and water. Nonetheless, it’s potential to contemplate changing CuSO4 with both anhydrous calcium sulfate (CaSO4) or anhydrous magnesium sulfate (MgSO4). An investigation was performed by Zhang et al. (2018) to check the desiccating functionality of anhydrous CaSO4 and MgSO4 to that of anhydrous CuSO4. The analysis discovered that the absorption of water by CaSO4 was better than that of MgSO4, and each had been considerably decrease than that of CuSO4. This means that whereas CaSO4 and MgSO4 might probably substitute for CuSO4, they’d not be as efficient at absorbing water from the pattern.
Moreover, anhydrous CaSO4 and MgSO4 can kind hydrates with water, whereas anhydrous CuSO4 doesn’t (Liu et al., 2016). Cont…..
