What is dihydrate process?
Descriptions of Process Characteristics i) Dihydrate process: Decomposition of phosphate rock with sulfuric acid and partially recycled phos- phoric acid is taken place under temperature of 70 – 80°C, stable range for diliydrate. Resultant slurry is filtrated and approx. 30% phosphoric acid and gypsum are obtained.
What is IMI process in the production of phosphoric acid?
The IMI process, for production of high-grade technical phosphoric acid, involves the attack of phosphate rock by hydrochloric acid. In addition to the most frequently used sulphuric acid, both hydrochloric and nitric acids can also be employed to digest phosphate rock to produce phosphoric acid.
What is quantitative requirement of sulphuric acid in production of phosphoric acid?
What is the quantitative requirements of sulfuric acid in production of phosphoric acid? Explanation: 93-98% of sulphuric acid is needed in the production of phosphoric acid, while 32% phosphate rock is needed.
What is phosphorous acid used for?
Phosphoric acid, also called orthophosphoric acid, (H3PO4), the most important oxygen acid of phosphorus, used to make phosphate salts for fertilizers. It is also used in dental cements, in the preparation of albumin derivatives, and in the sugar and textile industries.
Is H2PO4 a salt?
(Be sure you are able to write net ionic equations for these processes.) Salts containing the anion H2PO4‾ are weakly acidic. Salts containing the anion HPO4‾ are weakly basic.
Why is sulfuric acid used in fertilizers?
Uses of sulfuric acid By far the largest amount of sulfuric acid is used to make phosphoric acid, used, in turn, to make the phosphate fertilizers, calcium dihydrogenphosphate and the ammonium phosphates. It is also used to make ammonium sulfate, which is a particularly important fertilizer in sulfur-deficient.
Which is a use of Sulphuric acid?
In various concentrations the acid is used in the manufacture of fertilizers, pigments, dyes, drugs, explosives, detergents, and inorganic salts and acids, as well as in petroleum refining and metallurgical processes.
Is phosphorous acid strong?
While phosphoric acid is quite acidic, it is evident that it is, indeed, a weak acid because of the lack of full dissociation in water; a 1 M solution of strong acid would be around 0 (0 for monoprotic species, possibly less for diprotic due to an additional hydrogen ion).
Why is phosphorus reducing agent?
In phosphoric acid and its salts, phosphorus is in its maximum oxidation state of +5. Since phosphorus cannot be oxidised further to a higher state than +5, the acid cannot act as a reducing agent.

What foods you can dry in a dehydrator?
In a food dehydrator, you can easily dehydrate numerous varieties of food items like fruits, vegetables, herbs, spices, flowers, etc. The fruit that is dehydrated in this appliance is much reasonable than the preserved food that is available in the market.
What does a dehydration reaction typically produce?
Dehydration synthesis is also called as “ condensation reaction ” because both are characterized by the condensation and formation of water from the large molecule. Examples of dehydration synthesis reactions are the conversion of monosaccharides to complex sugars, production of proteins from amino acids,…
What are the methods of dehydration?
There are at least three commercial methods of natural gas dehydration, which are absorption, adsorption, and condensation. Absorption. Absorption is the most widely used industrial natural gas dehydration. Absorption is usually performed by using TEG (triethylene glycol).
What food can you dehydrate?
Most vegetables, with the exception of onions, mushrooms and tomatoes, should be blanched briefly before being dehydrated to limit discoloration and the risk of food-borne illnesses. You can dehydrate tomatoes, carrots, beets, greens, beans, squash, onions, peas, celery, corn, pumpkin and broccoli with good results.
