Genaue Bestimmung der Schwefelsäurekonzentration
ACCURATE DETERMINATION OF SULFURIC ACID WITHIN THE CHEMICAL, ACCUMULATORS, FERTILIZERS, METAL, AND PLASTICS INDUSTRIES The Density – Concentration Relationship of H2SO4 As the concentration of the Sulfuric Acid increases, the density also increases. This fairly linear relationship goes from 0% concentration up to approximately 96% or 97%. However, somewhere around 93% the linear relationship starts […]
