Analytical Sulphuric Acid (H₂SO₄)- 2.5Litres
Description:
-
Chemical Formula: H₂SO₄ (Sulfuric Acid) is a colorless, odorless liquid in its pure form. It consists of two hydrogen (H) atoms, one sulfur (S) atom, and four oxygen (O) atoms.
-
Concentration: Analytical sulfuric acid typically refers to a high-concentration, high-purity grade of sulfuric acid. It is available in concentrations around 95-98% by weight, with fuming sulfuric acid (also known as oleum) containing even higher concentrations.
-
Appearance: It is a colorless or slightly yellow liquid that is highly corrosive and can absorb moisture and water from the air, leading to potential fuming.
-
Purity: Analytical-grade sulfuric acid is manufactured to a high degree of purity, free from impurities, which makes it suitable for precise experiments, titrations, and chemical reactions.
Common Uses:
-
Titration: Analytical sulfuric acid is widely used in acid-base titrations to determine the concentration of alkaline solutions (like sodium hydroxide or potassium hydroxide).
-
Synthesis of Esters: Used in the production of esters by reacting alcohols with acids, which is a common reaction in organic chemistry.
-
Fertilizer Production: In the production of phosphoric acid (for fertilizers), sulfuric acid reacts with phosphate rocks to form phosphoric acid.
-
Sulfonation Reactions: Sulfuric acid is used in sulfonation processes in the production of detergents, dyes, and pharmaceuticals.
-
Cleaning and Pickling: Used in the pickling of metals, especially to remove rust, oxides, and other impurities from steel and iron.
Safety and Handling:
-
Highly Corrosive: Sulfuric acid can cause severe burns and permanent damage to tissues upon contact. Always wear protective gloves, goggles, and a lab coat when handling it. A face shield and fume hood are recommended for added protection.
-
Storage: Store sulfuric acid in airtight containers, preferably made of glass or plastic resistant to corrosion. Avoid contact with organic materials, metals, and bases, as it can react violently with them.
-
Spill Response: In case of a spill, neutralize the sulfuric acid with a baking soda or lime solution before cleaning up the spill. Always follow appropriate safety protocols.
