Detailed Product Description:
Sulphuric Acid (also spelled “Sulfuric”) is a colorless, dense, oily liquid with
a pungent odor. Noncombustible. Soluble in water. Very reactive. Mixing
with water generates exothermic reaction that cause significant temperature
rise in solution. Corrosive to most metals. Most commonly used for electrolytes
and metal cleaning.
Reactivity:
Sulfuric acid reacts with most metals via a single displacement reaction to produce
hydrogen gas and the metal sulfate. Dilute H2SO4 attacks iron, aluminum, zinc,
manganese, magnesium and nickel, but reactions with tin and copper require the
acid to be hot and concentrated. Lead and tungsten, however, are resistant to
sulfuric acid. The reaction with iron is typical for most of these metals, but the
reaction with tin is unusual in that it produces sulfur dioxide rather than hydrogen.
As an acid, sulfuric acid reacts with most bases to give the corresponding sulfate
(e.g., copper(II) sulfate).
Brand/Grade:
This is from Air Products and is semiconductor grade, high purity and
controlled for low particulate levels.
Precautions:
The corrosive properties of sulfuric acid are accentuated by its highly exothermic
reaction with water. Therefore, skin burns from sulfuric acid are potentially more
serious than those of comparable strong acids (e.g. hydrochloric or nitric acid), as
there is additional tissue damage due to dehydration and particularly due to the
heat liberated by the reaction with moisture in the tissue. The danger is obviously
greater with more concentrated preparations of sulfuric acid, but even the normal
laboratory "dilute" grade (approx. 1 M, 10%) will char paper by dehydration.

.
Strong irritant to eyes and skin. Toxic by inhalation and ingestion.
Use caution in mixing with water due to significant exothermic reaction
that can cause boiling and/or explosive spattering. Always add acid to
water and not the reverse.
