Q:Does the inorganic salt affect the gpc molecular weight results?
GPC determination of molecular weight through the column when the molecular size of the molecular peak, the molecular weight of the early comparison of the peak, that is relatively large molecules in the GPC pillars can not pass, pass the molecules were detected out of the peak, This molecular weight is not absolute, since the GPC determination is actually the size of the molecule rather than the size of the molecule, and of course it is also possible to approximate the molecular weight of the molecular weight of the molecule. Large; exactly how their relationship, with GPC can not be determined, only through the standard liquid molecular weight to compare, this result is relative, not absolute.

Q:Calcium is not an inorganic salt
Calcium salt is determined whether it is inorganic salt depends on its acid, if it is organic acid synthesis of calcium salt is organic salt, if it is inorganic acid synthesis of calcium salt is inorganic salt. The main basis for determining the inorganic salts is whether or not organic reactants are involved in the formation process.
Q:Advertisements related to inorganic salts -.-,
Calcium must be inorganic salt
Q:Which solvents have some solubility in inorganic salts
A wide variety of dyes, dissolved complex. The original dyes are organic, but some salt, some metal complexes, some of the larger molecules of the fused ring compounds, some polymer heterocyclic compounds, in some common organic solvents in the solubility is better than disperse dyes Raw dyes and oil-soluble dyes (this is actually the raw material of solvent pigments, strictly speaking, not dyes). There are basically additives in the finished dyes, such as direct dyes, acid dyes, reactive dyes, cationic dyes and other water-soluble dyes will be added inorganic salts, disperse dyes, reducing dyes will be added sulfonate sodium dispersant. In addition, the dye and other chemical products, their purity requirements are generally very low, will allow the presence of certain insoluble impurities. So the organic solvent can not be completely dissolved dye products really is very common or even a normal phenomenon.
Q:How to get an inorganic salt
Inorganic salts are salts of inorganic compounds, formerly known as minerals. Plant growth needs N, P, K three elements and Ca, Zn, B, Mg, S, Fe and other trace elements. Depending on the type and amount of inorganic salts required for plant life, the water and various proportions of inorganic salts are scientifically formulated into plant nutrient solutions. The method of cultivating plants with plant nutrient solution is called soilless cultivation. The inorganic salts used to prepare the nutrient solution are generally not available for extraction, such as potassium nitrate, calcium nitrate, magnesium sulfate, potassium dihydrogen phosphate, copper sulfate, zinc sulfate and the like, and the reagent may be a chemical fertilizer. The purity of the reagent is high and the impurities of the fertilizer are more. If you can not get it, you can use soil leaching solution (fertile soil plus fresh water, the liquid obtained after filtration), which generally contains a variety of inorganic salts.
Q:What is the disease of inorganic salt crystals?
It is recommended to drink boiled water.No need to take medication.
Q:What is the difference between inorganic and inorganic salts?
Inorganic salts are salts of inorganic substances, including salts produced by strong acids, salts produced by inorganic weak acids, and salts of small amounts of organic acids.
Q:Like the role of B, Fe, Mg, Ca, Mn, Cu, Cl, P, S, N ...., the more specific the better (college entrance examination range)
The various inorganic salts dissolved in the cells have a certain total concentration, such as human body fluid concentration of 0.9%, frogs of 0.65%, which for maintaining cell osmotic pressure, so that cells maintain a certain shape has an important role, too high or Too low will lead to cell due to water or dehydration to change the cell morphology. There are also a number of buffering systems in the body, which are a group which has a neutralizing effect on the added acid or base so that the pH does not change significantly and therefore plays an important role in maintaining the acid-base balance of the cells.
Q:Octopus why the lack of boron-containing inorganic salts can cause rape to flow only without fruit
Boron has a great influence on the reproductive process of plants, which can accelerate pollen differentiation and pollen tube elongation. In the absence of boron, pollen tube germination is affected, poor fertilization, which leads to the formation of seeds affected, the reduction of growth hormone produced by the reduction of growth hormone will affect the formation of fruit.
