Aluminum (sulfate, or sulphate) - a brief description, fields of use
Aluminum (sulfate, or sulphate) isa complex inorganic substance. It is white salt with a characteristic bluish tinge (let's say the shade is pink). Crystal hydrate is colorless. Hygroscopic. It dissolves fairly quickly in water.
A solution of aluminum sulfate is often used forpurification of water (with the coagulation of the impurities settle down and filter out already without problems), in the processing of textiles. In a slightly alkaline medium (as in neutral), it forms a precipitate (gelatinous insoluble pigment) used for staining the fabric and printing.
Aluminum (sulfate, or sulphate) perfectly neutralizes soil in a garden with an overestimated pH. This property is used by gardeners, seeking to re-flowering some types of flowers.
Aluminum (sulfate, of course) is included in a seriesantiperspirants. However, the question of its negative effect on the skin is being asked more and more often. It is believed that it is capable of causing irritation and even allergy when used frequently.
Aluminum sulphate (sulfate) is used andconstruction (as an accelerator, waterproofing). It is quite effective in combating slugs, mollusks, insects. Moreover, aluminum sulfate can be found in complex fertilizers. Without it, it is impossible to manufacture fire extinguishers. Some cosmetic companies use this substance in the production of their products (mascara, shadows).
In the food industry aluminum sulfateis in a number of additives-emulsifiers (under the name E-520). This substance, which is both a curing agent, and a means for removing the skin from the fruit, and a substitute for yeast. They clarify the water, process lobster and crab meat. And yet - this is an excellent tool to achieve a more dense consistency when preserving vegetables.
Aluminum sulphate technical (Al2 (SO4) 3)is obtained by the reaction of sulfuric acid and aluminum hydroxide. We can observe it in crystals (plates) and in an indefinite shape pieces up to 10 kg (second or third grade), however, usually this is a uniform bulk material (crystals up to 20 mm, higher grade).
First aid in case of aluminum sulfate poisoning suggests:
- washing of eyes or skin;
- exit from the poisoning area to fresh air;
- taking a glass of milk with further provocation of vomiting;
- Refer to a doctor.
Aluminum sulphate is stored in cool, dryplaces. The packaging must be tightly closed. Mixing with other substances is unacceptable (contact with bicarbonates, for example, is literally explosive).
