Description
Chromium sulfate is a colorless, oily liquid that is soluble in water, releasing heat upon dissolution. It is known for its corrosive properties, as it can cause damage to skin and metals.
Uses
Used in Chemical Industry:
Chromium sulfate is used as a chemical reagent for various applications, including the production of dyes, pigments, and wood preservatives. Its ability to dissolve in water and release heat makes it a useful component in these processes.
Used in Tanning Industry:
In the tanning industry, chromium sulfate is used as a tanning agent for leather. Its corrosive nature helps in the tanning process, providing a durable and resistant finish to the leather.
Used in Textile Industry:
Chromium sulfate is also utilized in the textile industry as a mordant, which helps to fix dyes onto fabrics, ensuring colorfastness and durability of the dyed materials.
Used in Electroplating:
Chromium sulfate is used in the electroplating process to provide a protective coating on metals, enhancing their resistance to corrosion and wear.
Used in Analytical Chemistry:
In analytical chemistry, chromium sulfate serves as a titrant for the determination of fluoride ions, thanks to its ability to react with these ions in a controlled manner.
Used in Photography:
In the photography industry, chromium sulfate is employed in the development process of photographic films, contributing to the formation of the desired image.
Used in Glass and Ceramics:
Chromium sulfate is used as a colorant in the production of glass and ceramics, imparting a characteristic green or yellow color to these materials.
Used in Agriculture:
In agriculture, chromium sulfate is utilized as a micronutrient supplement for crops, helping to improve their growth and yield by providing essential trace elements.
Used in Water Treatment:
Chromium sulfate is employed in water treatment processes, where it acts as a coagulant to help remove impurities and contaminants from water supplies.
Air & Water Reactions
Soluble in water with the release of heat.
Reactivity Profile
Oxidizing acids are generally soluble in water with the release of hydrogen ions. The resulting solutions have pH's of less than 7.0. Materials in this group react with chemical bases (for example: amines and inorganic hydroxides) to form salts. These neutralization reactions occur as the base accepts hydrogen ions that the acid donates. Neutralizations can generate dangerously large amounts of heat in small spaces. The dissolution of acids in water or the dilution of their concentrated solutions with water may generate significant heat. The addition of water acids often generates sufficient heat in the small region of mixing to boil some of the water explosively. The resulting "bumping" spatters acid widely. These materials have significant ability as oxidizing agents. but that ability varies (for example, from high for nitric acid to low for sulfuric acid and most sulfonic acids). They can react with active metals, including iron and aluminum, and also many less active metals, to dissolve the metal and liberate hydrogen and/or toxic gases. Like other acids, materials in this group can initiate polymerization in certain classes of organic compounds. Their reactions with cyanide salts and compounds release gaseous hydrogen cyanide. Flammable and/or toxic gases are also often generated by their reactions with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides, and weak or strong reducing agents. Additional gas-generating reactions occur with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), and even carbonates: the carbon dioxide gas from the last is nontoxic but the heat and spattering from the reaction can be troublesome. Acids often catalyze (increase the rate of) chemical reactions.
Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
Check Digit Verification of cas no
The CAS Registry Mumber 14489-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,4,8 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 14489-25:
(7*1)+(6*4)+(5*4)+(4*8)+(3*9)+(2*2)+(1*5)=119
119 % 10 = 9
So 14489-25-9 is a valid CAS Registry Number.
