May 22, 2024 · The formula mass of H2SO4 is calculated by adding the atomic masses of the elements present in the compound. For hydrogen (H), sulfur (S), and oxygen (O), the atomic masses are approximately 1, 32 ...

Jun 17, 2018 · 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.

May 31, 2024 · The way to work this is out is to first find the mass of one mole of H2SO4 .(98.08 grams). 10 grams is therefore 10/98.08 moles- = 0.102 moles of sulfuric acidEach mole of sulfuric acid contains ...

May 24, 2024 · 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 ...

May 20, 2024 · 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 ...

May 28, 2024 · Concentrated H2SO4 is 96 %.( In laboratory ) As density of concentrated H2SO4 is 1.84gm/ml we will need this number as well, and as the Atomic Mass of H2SO4 is 98.08,as it is dibasic for normality ...

Dec 3, 2024 · 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 ...

Mar 27, 2018 · $\begingroup$ @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. $\endgroup$ –

Jan 19, 2025 · H2SO4 is less strong than HClO4 because the sulfuric acid, H2SO4, is a diprotic acid, meaning it can donate two protons, while perchloric acid, HClO4, is a monoprotic acid that can donate only one ...

Jun 4, 2024 · Yes, lead (Pb) reacts with dilute sulfuric acid (H2SO4) to form lead sulfate (PbSO4) and hydrogen gas (H2). This reaction is a common method for testing the presence of lead ions.
