1. New people on the road first slowly, look and buy. Let's take a look
2. Of course, hydrogen is insoluble in water
because hydrogen is a non-polar bond
and water is a polar bond
when you learn the principle of Acacia compatibility
you will know that the non-polar bond is difficult to tolerate
the polar bond
3.

Good evening, burn skin, combustible, characteristic light red appearance, meet inorganic alkali neutralization proce exothermic, the third bottle of liquid is likely to be phenol. Phenol has strong irritation to human skin and mucous membrane, and has the phenomenon of burning white. Generally, it is a viscous oily liquid with bad smell, almost insoluble in water, and reaches the freezing point at a low temperature of more than ten degrees, which makes the whole bottle of solution present the appearance of crystallization. However, the first figure shows that the paint on the surface of the bottle cap has been dissolved. Generally speaking, phenol does not have this ability. It may be that it also contains a certain amount of halogenated hydrocarbons as diluents, such as chloroform and carbon tetrachloride - halogenated hydrocarbons are strong solvents, which can dissolve most non crosslinked single component polymers, such as acrylic acid, polyamide and aldehyde ketone resins on the surface of common cans, Moreover, adding water to the bottom also meets the physical conditions that the density of phenol and halogenated hydrocarbon is higher than that of water. Heating is not only phenol, but also halogenated hydrocarbon will have a lot of exothermic side reactions. Please refer to it as appropriate. The medical instry may use chloroform solution of phenol (chloroform has certain anesthetic and analgesic effect)< br />

4. Soluble in water
potassium dihydrogen phosphate is colorless tetragonal crystal or white crystalline powder. The relative density was 2.338. The melting point is 252.6 ℃. At 90 ℃, the solubility is 83.5g/100ml water, the aqueous solution is acidic, and the pH value of 1% potassium dihydrogen phosphate solution is 4.6. It is insoluble in alcohol. It has deliquescence. When heated to 400 ℃, it melts into a transparent liquid, and then solidifies into an opaque glassy potassium metaphosphate after cooling.
5. The ratio of H2S dissolved in water is: one volume of water dissolves 2.6 volume of H2S, and the solubility is not small.
however, the solubility of H2S in acid is much smaller than that in water.
therefore, it is possible to prepare H2S with acid by using the starter generator
6. Hydrogen molecules are difficult to dissolve in water. After dissolved in water, hydrogen mostly exists in the form of molecules in water, and a small amount exists in water as H3 + and H -.
7. Firstly, baso3 and BaSO4 are white precipitates insoluble in neutral solution (so-called insoluble in water). However, baso3 is soluble in acid solution, while BaSO4 is insoluble in acid solution. Baso3 dissolves in acid solution, and the equation is baso3 + 2H + = Ba2 + + H2O + SO2, that is, strong acid makes weak acid. In addition, the tetravalent sulfur in baso3 has strong recibility and can be oxidized by many oxidants, such as nitric acid, ferric oxide, permanganate, hypochlorite, peroxide and so on. As a result, white precipitates will appear when SO2 is introced into some acidic solutions. For example, when SO2 is introced into the mixed solution of BA (no) 3 and HNO3, white precipitates will be generated. This is because baso3 is oxidized to BaSO4, resulting in acid insoluble white precipitates. In real life, BaSO4 is used to test gastrointestinal, also known as barium meal, which is based on the principle that BaSO4 is insoluble in hydrochloric acid (the main component of gastric acid).
8. No,
add a certain mass of substance to a certain amount of water to see if the mass of solid decreases. If the mass decreases, it will dissolve in water. If not, it will not dissolve,
9. It can (except carbon)
white phosphorus is insoluble in water, soluble in carbon disulfide
sulfur is insoluble in water, slightly soluble in alcohol, soluble in sodium sulfite solution (with chemical reaction to form sodium thiosulfate)
rubber is soluble in benzene, toluene, xylene
silver chloride is soluble in liquid ammonia
there are many more
but carbon seems to be insoluble in any solvent
