Accurate Determination of Sulfuric Acid Concentration
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 linearrelationship goes from 0% concentration up to approximately 96% or 97%. However, somewhere around 93% the linear relationship starts to […]
