Reagent Sulfuric Acid 41% is a high-purity acid solution (typically meeting ACS specifications) that delivers moderate acidity with low viscosity, minimal fuming, and very low heat generation upon dilution. This specific concentration is particularly convenient for preparing lead-acid battery electrolyte, performing analytical procedures that require precise moderate acid strength, and carrying out mild chemical transformations where aggressive charring or dehydration must be

Reagent Sulfuric Acid 60% is a high-purity acid solution (typically meeting ACS specifications) that offers a practical balance between strong acidity and safe handling. With reduced fuming, lower viscosity, and a lower heat of dilution than 9698% grades, it serves as a versatile stock acid for preparing more dilute solutions, carrying out analytical digestions, and performing moderately strong acid-catalyzed reactions without the extreme aggressiveness of concentrated acid.
