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

5.FAQ
1, how about your packing?
My main packing is 25kg or 1000kg PP PE or kraft bag , with or withour pallets,with or without anticaking. We also can make packing and shipping mark are your ask, such as 50kg/50bl bag.
2, how long time you can make the shipping?
We can make the shipping within 5-10day after confirm the order.
3, why you buy from me?
We have stable quolity and price, not best quolity and price. It is not true for best quolity and best price. Our factory is manufacture according the BP USP and FCCIV terms. We have in this line for more than 8 years. We are one of the biggest exporter from Qingdao port.
- Q: Several kinds of inorganic salt food sources?
- Milk containing calcium, spinach iron, kelp containing iodine, oysters containing zinc, carrots containing A, tomatoes containing C, mushrooms with B1, sun can get D
- Q: I'm said that with the increase of temperature the inorganic salts will decrease. Will that be correct?
- Usually solubility will increase with increasing temperature but there are a significant number of exceptions which show the opposite.
- Q: What is the physiological function of inorganic calcium
- Maintain the life of cells and organisms
- Q: Children eat what to add the body of inorganic salts
- Such as fruits, vegetables, beans or soy products, kelp, eggs and so on. Eat hot and humid food: watermelon, bitter gourd, peach, ebony, strawberry, tomatoes, cucumber, mung bean and so on.
- Q: Which foods contain calcium-containing inorganic salts
- Calcium and inorganic salts are two concepts, bother you to go back and turn the chemical book and then ask, inorganic salt can eat
- Q: Organic chemistry extraction lab. If the KBr wasn't there I would just add HCl to protonate the NH2, but I'm not sure if that will affect the KBr or the carbon chain. Both of these are in an aqueous phase.
- The amine will certainly coordinate to K+, but the interaction is not very strong and hydrogen bonding from water will compete efficiently. Also, if your amine is soluble in water, you are not going to be able to isolate it by turning it into the corresponding ammonium salt.
- Q: What is the composition of inorganic salts?
- Inorganic salts are mineral nutrients that are present in the body and in food
- Q: citrate, What is the rationale for using a medium with this type of composition for the performance of the citrate utilization test?Thank you!
- Simmons Citrate Medium
- Q: What is the disease of inorganic salt crystals?
- It is recommended to drink boiled water.No need to take medication.
- Q: A. oxygen demanding wastesB. organic plant nutrientsC. inorganic plant nutrientsD. water soluble inorganic chemicalsE. sediment
- Acids, D. water soluble inorganic chemicals salts, D. water soluble inorganic chemicals metals E. sediment
