Thread Content
What are the possible industrial uses for sulfuric acid with a 75% concentration that meets the specifications for analytical grade? Besides manufacturing batteries?
It can be concentrated before use, or it can be used as fertilizer
Are batteries and fertilizers demanding regarding acid concentration? Does the quality of the acid affect the quality of the product?
Batteries have high requirements regarding the purity of sulfuric acid; high-purity sulfuric acid is necessary. The same high standards apply to fertilizers, as well, with requirements concerning the levels of organic substances and heavy metals
Magnesium sulfate generally uses 60% acid as a component in compound fertilizers
Analytically pure material is better for use as a reagent; even at lower concentrations, it can be used as a raw material for producing other sulfate reagents
