2.Main Features of Sodium Hydrosulfite：
It is a versatile chemical that's used in the manufacture of a variety of products we all use every day,
from photographic film to wine; from fine writing papers to leather goods; from colored fabrics to metal recovery.
While the applications for this chemical workhorse are as vast and as varied as the industries that use it,
in most cases, sodium hydrosulfite performs one of the following three roles:
1) As reducing agent, hydrosulfite chemically reduces othercomponents by donating an electron or electrons
2) As sulfonating agent, hydrosulfite adds sulfur to another chemical compound
3) As cation source, hydrosulfite adds a cation, or sodium, to a product system

- Q: How does inorganic salts maintain osmotic pressure and pH
- Osmotic pressure to the concentration of inorganic salts affect the distribution of water molecules inside and outside the cell ~ to adjust the osmotic pressure, when the extracellular fluid concentration is greater than the intracellular fluid when the performance of water loss, otherwise the water.
- Q: CuMnFeNior ZnAlso metal calcium reacts with molecular hydrogen to form a compound. Which statement concerning this compound is not true?It's formula is CaH2it is ionicsolid at room tempwhen added to water, reacts to produce h2 gaswhen added to water, forms acidic solutionMy guess was going to be that it is not ionic, but i'm not 100% positive.Can anyone help me with these chemistry questions? Or atleast point me to some webpage that might help. Please and thank you.
- Only Zn compounds form colorless or white salts. The second question would be the last answer, which is false. It forms an alkaline solution when added to water.
- Q: For science I have to find out what salts are used for but when i search a salt like lithium sulphate it always comes up with "would you like to buy" could you please tell me what these salts are used for*lithium sulphate*zinc nitrate*sodium phosphate
- HI I'M PNT. LITHIUM SULFATE is a white inorganic salt with the formula Li2SO4. It is used to treat bipolar disorder. It is soluble in water, though it does not follow the usual trend of solubility versus temperature — its solubility in water decreases with increasing temperature . This property is shared with few inorganic compounds, such as the lanthanoid sulfates. Lithium sulfate crystals, being piezoelectric, are also used in ultrasound-type non-destructive testing because they are very efficient sound generators. However they do suffer in this application because of their water solubility. ZINC NITRATE: Zinc nitrate (Zn(NO3)2) is a chemical compound used as a mordant in dyeing. It is also a source of zinc ions for chemistry. An example reaction gives a precipitate of zinc carbonate:Zn(NO3)2 + Na2CO3 → ZnCO3 + 2 NaNO3. Conditions/substances to avoid are: reducing agents, organic materials, metal powders, heat and flame, cyanides, sodium hypophosphite, tin(IV) chloride, phosphorus, thiocyanates, carbon, and sulfur. Its Relative Molecular Mass is 189. SODIUM PHOSPHATE: Sodium phosphate are forms of phosphorus, which is a naturally occurring substance that is important in every cell in the body. Sodium phosphate is used to treat constipation and to clean the bowel before surgery, x-rays, endoscopy, or other intestinal procedures. Sodium phosphate enemas are also used for general care after surgery and to help relieve impacted bowels. Sodium phosphate may also be used for other purposes not listed in this medication guide REGARDS, PNT.
- Q: People do not eat salt tears with no inorganic salt
- Your body depends on sodium ions for a variety of regulation, including the transmission of nerve signals, etc., before you tears do not contain salt before you have a dog
- Q: What is the composition of inorganic salts?
- Inorganic salts are inorganic compounds in the salt, formerly known as minerals
- Q: how come a penny can hold more drops of the salt water solution than just plain tap water from your faucet?
- Put in in a narrow tube. The narrower it is, the more surface tension it has at the meniscus.
- Q: Are the inorganic salts mineral and they are soluble in water?
- Generally speaking, inorganic salts, including minerals, inorganic salts are not minerals. Some inorganic salts can be soluble in water and some can not, the vast majority of minerals do not dissolve in water, otherwise the rain on the rocks are not dissolved Is it gone?
- Q: Seaweed, kelp, shrimp and other seafood, the content is more of the kind of inorganic salts
- Iodine is an important material for the synthesis of thyroid hormones, the body long-term iodine deficiency will affect the thyroid hormone synthesis and thyroid development, will be endemic goiter, that is, big neck disease. Kelp, seaweed and other marine algae are rich in iodine, so eat kelp, seaweed and other iodine-rich foods can prevent big neck disease
- Q: salt is organic or inorganic?
- inorganic
- Q: The addition of inorganic salt viscosity of micelles increased first and then increased again and then reduced, there is no possibility ah? Yes, then what is the reason for the increase ah?
- possible. The inorganic salt is dissolved in water to form positive and negative ions, and the ions of the micelles are extruded to make the solubility smaller and form an increase in the viscosity. With the increase in the amount of inorganic salt, it does not have the ability to dissolve in water, there is no micelles and the molecular state exists in the water, the liquid becomes thin ...
