Sulfuric acid is a colorless, corrosive liquid with the chemical formula H2SO4. It has various industrial uses including pH adjustment and cleaning. Proper personal protective equipment should be worn when handling sulfuric acid due to its corrosive properties. Sulfuric acid requires careful storage and labeling according to safety guidelines to prevent harm to people and the environment.

2. Properties
 Chemical formula H2SO4
 pH (1% soln/water): Acidic.
 Specific Gravity: 1.84 (Water = 1)
 Color: Colorless.
 Solubility: Easily soluble in cold water
(Exothermic rection).
 Class 8 – Corrosives.

3. Function
 PH adjustment controlling and cleaning
agent for scales
 Used For
 U/S of automatic filters “PH adjustment” 7-8.6
 CEB for U.F “anti-scalant”
 Regeneration of Polisher “source of H+ group for
cations replacement”

In case of fire: keep
drums, etc., cool by
spraying with water but
NO direct contact with
water.
Risk of fire and explosion on
contact with base(s) ,

See Chemical Dangers.
May be stored in stainless
steel containers. Store in
an area having corrosion
resistant concrete
floor. Keep container
tightly closed. Keep
container in a cool, well
ventilated area.
Stop leak if without risk.
Absorb with inert material. Do
not get water inside container.
Do not touch spilled
material. Use water spray
curtain to divert vapor drift.
Use water spray to reduce
vapors. Prevent entry into
sewers, basements or
confined areas; dike if
needed. Neutralize the
residue with a dilute solution
of sodium
carbonate.

7. Environmental considerations
 Prevent from entering in public sewers
or the immediate environment.
 Do not empty into drains, dispose of
this material and its container to
hazardous or special waste collection
 Point according to Hazardous Waste
Regulations.

18. Attention
 Concretes made of cement are highly alkaline with
pH values normally above 12.5 and are not easily
attacked by acidic solutions. As the pH of the
solution decreases the equilibrium in the cement
matrix is being disturbed, and the hydrated cement
compounds are essentially altered by hydrolytic
decomposition which leads to the severe
degradation.
 Taking sample from sulfuric truck to detect the iron
in sulfuric sample, Rust is an iron oxide, usually
red oxide formed by the redox reaction
of iron and oxygen in the presence of water or air
moisture.
