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:Why are inorganic sodium salts much better soluble in ethanol than potassium salts?

Sodium ions are smaller cations than potassium ions. Ethanol has a polar bond in the OH, but it also has a nonpolar tail, the ethyl group. So, unlike water, that has two OH groups that are polar and can interact with cations, ethanol has only one, so it requires strong electrostatic attractions to form a hydrogen bond - dipole interaction with any cation that it encounters. Being smaller, the sodium ions have their positive charge concentrated over a much smaller volume, so the polar OH bond in ethanol is more strongly attracted to the concentrated charge of the sodium than to the diffuse charge of the potassium ion, making the salt more soluble in this solvent.

Q:What is the difference between chemical monomer and elemental

The monomer is the basic unit that forms the polymer, usually the organic compound. Elemental is pure matter that contains only one element.

Q:What is the acid egg

1 vinegar egg preparation to take fresh eggs 10, 9 degrees vinegar (or local quality vinegar) 500ml, honey or sugar amount. With alcohol disinfection of eggs into the porcelain containers, and then into the vinegar, sealed 48 hours, until the eggshell softened, only thin egg wrapped in swollen eggs, unsealed, the egg skin smashed, the egg white, Egg yolk and vinegar mix, then placed after 24 hours available. 2 use method to take vinegar egg 40 ~ 50ml, plus 2 to 3 times the warm water, plus the right amount of honey or sugar, feeding a day, once every 10 to 15 days can be. 3 cases on March 5, 1999, a farmer 1 pig susceptible treatment. Symptoms: normal body temperature, loss of appetite, defecation difficulties, often for defecation posture, sometimes discharged dry and small dung ball, and with white or red brown mucus, urine deep yellow and small, palpable abdominal touch To the large intestine with dry hard feces, diagnosed as constipation. Then with rhubarb 100g, fruit guide 10 feeding service, intramuscular injection VB1 10ml, once every 3 days, although the constipation has been alleviated, but a week later, the symptoms as early as possible. Second consultation in the original drug on the basis of plus Ma Ren 12g, talc, rhubarb, Yuan Mingfen, Citrus aurantium 9g, Jianshui feeding service, once every 3 days, still ineffective. Finally diagnosed as habitual constipation, then the law of the use of vinegar egg treatment for 10 days, told more, no recurrence. 4 experience vinegar egg drawn easy, affordable, effective, can be widely used in habitual constipation, constipation caused by infectious diseases, antibiotics should be based on the treatment, with the application of vinegar egg, the effect will be more satisfied.

Q:People lack the inorganic salt will be what disease

Calcium deficiency can lead to osteomalacia, osteoporosis, etc., can also lead to convulsions.

Q:To sweet to take the sugar cans, to the acid to take the altar altar. What is this sentence?

Is not the need to take what ah Want to take sweet sugar cans, meaning to get their own sugar cans, so it is their own to take what they need, is to take what they need.

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:What fruit contains more minerals?

Watermelon fruit contains 90% or so, so there are "watermelon," said watermelon contains a variety of nutrients and chemical substances. Watermelon pulp contains protein, sugar, crude fiber, potassium, phosphorus, calcium, iron, sodium, magnesium Chlorine, niacin, vitamin A, vitamin B1 and vitamin B2 in the watermelon juice also contains citrulline, alanine and glutamic acid and other amino acids, malic acid and other organic acids, pectin and a small amount of glycosides, and Medlar, cinnamon and other alkaloids and so on.

Q:I am told to find which bottled mineral water brands contain the most mineral salts.But im not sure if the mineral salt here is talking about the common table salt (Sodium Chloride) or the chemical salt (ionic compounds such as sulfate and chloride) or the whole list of dietary minerals (potassium, chlorine, calcium, magnesium, ect.) I normally think it is just the table salt but im afraid I might get wrong. So what is the exact definition?

it okorder /C005969/mi... "Mineral salts are inorganic (carbon-free) elements that turn to ash when burned. "
