FAQ

Indicating the organic compounds and inorganic salts in the boiling point, melting point and solubility of what is the difference

Organic compounds are mainly covalently bonded, the mutual attraction between molecules is very weak, so its melting point, low boiling point, generally insoluble in water and soluble in organic solvents. Inorganic salts with ionic bonding, positive and negative ions electrostatic attraction is very strong, so the melting point, boiling point is very high, usually insoluble in organic solvents and soluble in water.

Is urea an inorganic salt?

Is not organic matter ah inorganic salts are present in the body and food minerals in the mineral, composed of organic matter and inorganic synthesis of the human body has been found to have more than 20 kinds of essential inorganic salts, about 4 to 5% of body weight. More (> 5g) for calcium, phosphorus, potassium, sodium, chlorine, magnesium, sulfur seven; daily dietary requirements are more than 100mg, known as constant elements. Other low content, with the modern analysis of technological progress Iron, copper, zinc, manganese, cobalt, molybdenum, selenium, chromium, nickel, silicon, fluorine, vanadium and other elements were found by atomic absorption spectroscopy, neutron activation, plasma emission spectroscopy and other trace analysis methods. But also the human body is necessary, the daily dietary requirements for the amount of μg ~ mg called trace elements.

Is the inorganic salt the same as the saline?

Saline is sodium chloride solution, most people use the point is 0.9%.

Does the urine and urine contain inorganic salts? Anxious

Analysis: This question can be solved from the formation of urine. Kidney is the formation of urine organs, nephrons are the basic unit of renal structure and function, nephrons include glomerular, renal sac and renal tubules; urine formation process, including filtration, reabsorption and secretion of three processes.

And what I specifically need are salts with Bromide, Chloride, Phospate and Carbonate ions.Thanks for any help.

That list is near endless. There are countless inorganic cations and organic groups that can combine with these ions. Pretty much every metallic element in the periodic table will form cations with bromide and chloride. Not sure about phosphate, but most metals will bind with it. Carbonate will be trickier, as some ions are too acidic and will decompose the carbonate (iron(III) is an example, and it will form the oxide instead, liberating CO2 in the process). Aside from simple elemental ions, there are also polyatomic cations (such as ammonium) and lots of complexes that will form compounds with these anions.

Do inorganic mercury salts bioaccumulate?

Yes they do bioaccumulate. Mercury builds up for years and years, and eventually sits in a residue of pure mercury. - JJ

Sodium bicarbonate is not an inorganic salt

Yes, organic refers to salts with carbon skeleton chains other than carbon and carbon oxides and carbonates, so sodium bicarbonate is an inorganic salt

what is the function of salts in DNA extraction?

The role of the salt is to neutralize the charge of the DNA's sugar phosphate backbone. This makes the DNA less hydrophilic (less soluble in water). Ethanol has a lower dielectric constant than water so it's used to promote ionic bonds between the Na+ (from the salt) and the PO3- (from the DNA backbone) causing the DNA to precipitate, to extract DNA finally..
