2024年12月3日 · MW of H2SO4 is 98.08. 2M = 2 x 98.08 in 1 L of water (1 gram=1 ml). Take 500 ml water in a 1 L measuring cylinder. Add 196.16 ml slowly along the side into water in the measuring cylinder. Use 50 ...

2018年6月17日 · My question is, why can't the dissociation reaction happen like this: $$\ce{H2SO4 -> 2H^+ +SO4^{2-}}$$ I know hydrogen is a diatomic gas, but here I don't know if H will dissociate as a gas or as a liquid (since $\ce{H2SO4}$ is a liquid, not a gas). I'm trying to learn, thank you for your understanding and your time.

2024年12月8日 · To prepare 1M sulphuric acid from concentrated sulphuric acid:First consider the molecular weight of H2SO4 = 98 g/mol, so you have to add 98g of conc. acid and make up to 1 liter of water (as ...

2024年5月20日 · Hydrochloric acid (H2SO4) is a strong acid that can cause severe burns if it comes in contact with the skin. In combination with 3M, which is a type of mask, the H2SO4 can cause the mask to ...

2016年10月11日 · The decomposition of $\ce{H2SO4}$ to $\ce{H2O}$ and $\ce{SO3}$ is predominant between $400$ and $700\ \mathrm K$. The formation of a small amount of gaseous sulfuric acid can be observed. Above $673\ \mathrm K$, the equilibrium constant of the reaction R1 becomes higher than 1 and increases rapidly. $$\ce{H2SO4 <=> H2O + SO3}\tag{R1}$$

2012年8月27日 · In the $\ce{H2SO4}$ molecule, two bonds are simple covalent ($\ce{S-OH}$ ones), and two are dative ($\ce{S-O}$ ones). A common concept of electron unpairing to my knowledge is proved broken by quantum chemistry calculations and spectral experiments for hypervalent compounds of $\ce{P}$ and $\ce{S}$.

$$\ce{CH3CH2OH <=>[H2SO4] CH2=CH2 + H2O}$$ Now, using Le Châtelier's Principle, we can deduce Dissenter's comments. In concentrated sulfuric acid there is little to no water (note that we also start off with little to no ethylene). The equilibrium shifts to produce products. In dilute sulfuric acid there is lots of water (and little to no ...

2018年3月27日 · $\begingroup$ @Molly The testube was clean.Well ,I added H2SO4 first and then added the HCl.The resultant liquid was slighly lighter than the HCl colour and loads of the white fumes was emmited,though the reactants were small in quantity.Even with the ventilator fans on,the gas pretty much covered the room. $\endgroup$ –

2013年4月20日 · Edit: Another neat consequence of the acidity strength argument is that it explains why the reactions stop at the bisulfate anion instead of going all the way to the halide sulfates; $\ce{HSO4-}$ is a much, much weaker acid than $\ce{H2SO4}$, so there is no free energy to lose out of consuming it to produce a much stronger acid (in the case of ...

2024年5月24日 · H2SO4 is Sulfuric Acid. If it has the number 2 in front of the whole compound it means there are two molecules in the reaction. The number of atoms in 1 molecule is (2 x hydrogen, 1 x sulfur, 4 x ...
