Is methanesulfonic a strong acid?
Is methanesulfonic a strong acid?
Methanesulfonic acid (MSA), the simplest alkanesulfonic acid, is a hygroscopic colorless liquid or white solid, depending on whether the ambient temperature is greater or less than 20 ºC. In aqueous solution, it is a strong acid (completely ionized).
What is the pKa of methanesulfonic acid?
-2.0

What is the geometry of the sulfur atom in methanesulfonic acid?
Molecular Shape in the H2SO4 molecule, Sulfur being the central atom has four paired electrons and 0 unpaired electrons. Hence, its structure is classified as a tetrahedron with 109.5 degrees between the Sulfur and the four Oxygen atoms.
Is Hydronium the strongest acid?
H3O^+ is the strongest acid in aqueous solution.

What happens if you get methanesulfonic acid on your face?
Causes severe skin burns and eye damage. May be corrosive to metals. Harmful if swallowed. Harmful in contact with skin. May cause respiratory irritation. Wear protective gloves/protective clothing/eye protection/face protection. Remove/Take off immediately all contaminated clothing. IF ON SKIN: Gently wash with plenty of soap and water.
The pKa of methanesulfonic acid is -1.86, indicating that this compound will exist almost entirely in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts. Volatilization from moist soil is not expected because the acid exists as an anion
How is methanesulfonic acid produced in the atmosphere?
Methanesulfonic acid is produced by atmospheric hydrolysis of dimethyl sulfoxide (1), which itself is produced from the atmospheric photochemical oxidation of dimethyl sulfide, which comes from marine algae and salt marsh plants(2).
