Q:A colorless solution contains which inorganic salt?
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:The lack of symptoms and food sources of several inorganic salts
Food sources of inorganic salts containing calcium Source: dairy products, beans, cereals, kelp and so on. Source: seafood, etc. Food of iron-containing inorganic salts Source: Fruits Containing iodine-containing inorganic salts Source (trace): seaweed, jellyfish, corn, mussels, etc. Zinc-containing inorganic salt food sources (trace): animal liver (viscera), fruit, peanuts, etc.
Q:Where can I find a list of all inorganic salts?
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.
Q:Effect of Inorganic Salts on Viscosity
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 ...
Q:would heterotrophic organism grow well in inorganic salt media? why or why not?
No. Heterotrophs get energy from the environment in the form of chemical bonds within organic molecules (such as glucose). An inorganic salt medium would not supply the needed organic molecules. Your heterotroph would starve.
Q:are acids, bases, salts and oxides belong to inorganic compound?
Organic compounds are anythng with carbon C in them. Acids or bases can be organic or inorganic depending on if they have a carbon atom in them. Salts result from a reaction of an acid and a base e.g. Sodium chloride NaCL results from a reaction of HCL and NaOH i.e. HCL + NaCL = NaCL + H20. A reaction involving an acid and a base results in a salt and water as shown above. So compounds are organic if they have carbon in them, including the oxides
Q:The lack of three major inorganic salts can cause symptoms in the plant
Nitrogen: to promote cell division and growth, so that leaves grow lush. Lack of performance: plant thin and thin, leaves yellow, severe leaves were light brown.
Q:What are minerals and trace elements?
81 species were detected on the basis of the human body. 81 kinds of elements in the body of the arrangement is very tight combination, and more less will not work. Human anatomy found that there are 74 kinds of serum, 54 kinds of brain, 49 kinds of heart, 50 kinds of liver, thymus 18 species. They constitute the most basic unit of the human body, human life, old, sick, dead and all elements related to the body. According to the elements in the human body content is different, can be divided into macro elements and trace elements two categories. Accounting for more than 0.01% of the total body weight of the elements, such as carbon, hydrogen, oxygen, nitrogen, calcium, phosphorus, magnesium, sodium, etc., called macro elements; , Zinc, copper, manganese, chromium, selenium, molybdenum, cobalt, fluorine, etc., known as trace elements. Trace elements in the human body content is really minimal, such as zinc only the total weight of the human body of thirty-three parts per million. Iron is only sixty thousandths.
Q:Will a potassium ion from the inorganic salt KBr attach to NH2 at the end of a carbon chain?
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 are the differences between inorganic salts and salt?
Is an inorganic salt of inorganic salts by metal cations and non-metallic anions or ammonium ions and non-metallic anion compounds. Sodium chloride is a kind of inorganic salts!
