Accurate Concentration Basic Inorganic Chemicals 94 Percent Sulfuric Acid Clear Oily Liquid

is a high-purity grade (often meeting ACS or similar specifications) with slightly lower concentration than 96–98% grades, making it convenient for applications requiring precise dilution or moderate acidity. Its main uses are:

• General Reagent: Preparation of diluted acid solutions, pH adjustment, and standard acid titrations.

• Sample Digestion: Used in COD (Chemical Oxygen Demand) and Kjeldahl nitrogen determinations, where controlled acidity is required.

• Desiccator Drying Agent: Maintains a dry atmosphere in laboratory desiccators.

• Esterification, Nitration & Sulfonation: Acts as a catalyst and dehydrating agent in the manufacture of pharmaceutical, fragrances, and dye intermediates, where the 94% strength offers safer handling and easier dilution than 96–98% grades.

• SPM (Sulfuric Peroxide Mixture) Preparation: Mixed with hydrogen peroxide for wafer cleaning and photoresist stripping; the 94% concentration simplifies the calculation and mixing of optimal cleaning solutions.

• TOC Analysis: As an acid reagent for inorganic carbon removal.

• Water Quality Test Kits: Pre-treatment acid for colorimetric or titrimetric determination of parameters like phosphate, ammonia, and metals.
