Sulfuric Acid

Size:

Color:

Product Short Description: Purified sulphuric acid manufactured by various filteration process by unique features.
Product Technical Specification:
Remarks:

Sulfuric Acid is a strong acid in terms of chemical ionization and solutions of it can be assayed using a strong base, such as Sodium Hydroxide or Potassium Hydroxide. The endpoint can be determined potentiometrically or by using a pH indicator. The selection of the indicator used depends on the initial concentration of the Sulfuric Acid and the strength of the alkali used. This is due to the fact that the Normalities of the acid and the base affect the shape of the neutralization curve that results during the titration.The sulphuric acid manufactured by us has unique features.  It has a bright yellow colour and is of Russian Grade/ gost 127. 1-93. Its refinery speciation is as follows.Purified sulphuric acid manufactured by various filteration process with unique features.
