H2so4 melting point
Because the hydration reaction of sulfuric acid is highly exothermic, dilution should be performed by adding the acid to the water rather than the water to the acid, to avoid acid splashing. Because the reaction favors the rapid protonation of water, addition of acid to the water ensures that the acid is the limiting reagent. This reaction may be thought of as the formation of hydronium ions: Websulfuric acid, sulfuric also spelled sulphuric (H2SO4), also called oil of vitriol, or hydrogen sulfate, dense, colourless, oily, corrosive liquid; one of the most commercially important of all chemicals. Sulfuric acid is prepared …
H2so4 melting point
Did you know?
WebThe melting point and boiling point of H2SO4 are 283.46 K and 610 K respectively. It is miscible in water and the process is exothermic because some amount of heat is generated. The vapor pressure of H2SO4 is 0.001mmHg at 20 0 C. the pKa 1 and pKa 2 of H2SO4 are -2.8 and 1.9. so, from the value of pKa, we can say that it is a very strong acid. WebAug 11, 2014 · So, the compound above that will have the highest melting point will certainly be an ionic compound, either N a C l, C a F X 2 or S r C l X 2. I thought that I should calculate the molar weight but that won't work, because the correct answer is C a F X 2, and S r C l X 2 has a greater molar weight.
