What is the freezing point of sulfuric battery acid?
2013年4月9日 · Batteries have water-sulfuric acid solutions. There freezing point of water-sulfuric acid solutions varies as a function of concentration in an unusually complex way, having plural local minima and maxima. This is because the solid has eight identified phases: $\ce{H2O}$ $\ce{H2SO4 * 6 H2O}$ $\ce{H2SO4 * 4 H2O}$ $\ce{H2SO4* 3 H2O}$ $\ce{H2SO4 ...
inorganic chemistry - Why is the boiling point of sulfuric acid …
2016年3月10日 · • The boiling point of sulfuric acid is 337 °C (639 °F; 610 K) When sulfuric acid is above 300 °C (572 °F), it will decompose slowly. • The boiling point of phosphoric acid is 158 °C (316 °F; 431 K) When phosphoric acid is above 213 °C (415 °F; 486 K), it will decompose slowly.
safety - is it possible to store formic acid longer if frozen ...
2015年3月25日 · Lowering the temperature would reduce the decomposition rate from both a thermodynamic and kinetic point of view. The MSDS I have looked at indicate that the bottle should be vented periodically to release the pressure built up from decomposition. However this one also says that formic acid should not be stored below its freezing point of 8C.
How does H2SO4 dissociate? - Chemistry Stack Exchange
2018年6月17日 · $\ce{H2SO4}$ is one of common strong acids, meaning that $\ce{K_{a(1)}}$ is large and that its dissociation even in moderately concentrated aqueous solutions is almost complete.
Question about vapor pressure in solids and liquids
2023年6月14日 · The differences manifest in the latent heats of melting and vaporization. [It seems that the place to study this is in microgravity, freefall, in a vacuum; or at the critical point.] In a pure water system [A one component system]: ice, water and vapor coexist only at the triple point. At the triple point all 3 phases have the SAME CHEMICAL ...
solubility - If i keep adding sulfuric acid into water, will it keep ...
2018年5月10日 · When you dissolve a small amount of sulfuric acid in water then a chemical reaction occurs. The sulfuric acid dissociates into hydrogen cations (H+) and hydrogen sulfate anions (HSO4-). At very low concentrations of sulfuric acid in water the conductivity of the water is proportional to the sulfuric acid concentration.
Obtaining 30% sulfuric acid - Chemistry Stack Exchange
2017年12月8日 · $\begingroup$ 10% solution means that it has a procentile mass of 10% sulfuric acid mixed with water, the same being with 50%, so by finding the mass of the whole solution 300 and multiplying it by ρ of the selected solution you get the whole mass of the solution which is 420 and that multiplying by 0.5(50%) you get 210grams of H2SO4 $\endgroup$
Why is hot concentrated sulfuric acid preferable to cold?
2015年11月13日 · The effect of heating the sulfuric acid depends on the metal (e.g. steel is good for up to 25C 60-95% sulfuric acid) but there the trans-passive region where metals such as iron no longer have a protective layer. This is due to instability of the …
