How does H2SO4 dissociate? - Chemistry Stack Exchange
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.
How do you prepare 2N H2SO4 and 2M H2SO4? - Answers
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 ...
How do you prepare 1M sulfuric acid from concentrated ... - Answers
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 ...
What is the chemical structure / hybridization of sulfuric acid?
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 $\ce{S}$.
How do you make 3M H2SO4? - Answers
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 ...
What is the observation when H2SO4 reacts with MgCl2?
2024年6月1日 · The chemical reaction for Magnesium (Mg) in Sulfuric acid (H2SO4) is given by the equation: Mg + H2SO4 ---> MgSO4 + H2 gas. The products of this reaction are Magnesium Sulfate (MgSO4, a salt) and ...
Cyclisation of acetone on reaction with conc. H2SO4
2019年12月21日 · Mechanism for reaction of acetone with concentrated $\ce{H2SO4}$: The product is supposed to be mesitylene, and on various sites I found the reason behind it to be aldol condensation And some sites provided me with unusual products( as for a high school student)
organic chemistry - Why concentrated sulfuric acid for …
$$\ce{CH3CH2OH <=>[H2SO4] CH2=CH2 + H2O}$$ 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 ...
Mixing hydrochloric acid and sulphuric acid, both concentrated
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. $\endgroup$ –
How does sulfuric acid react to heating? - Chemistry Stack Exchange
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. $$\ce{H2SO4 <=> H2O + SO3}\tag{R1}$$
