Question

way is dilute sulphuric acid added while preparing a standard solution of mohrs salt? short answer questions​

Answer 1

Answer:

Sulfuric acid or sulphuric acid, also known as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with molecular formula H₂SO₄. It is a colourless and viscous liquid that is soluble in water and is synthesized in reactions that are highly exothermic. Wikipedia

Formula: H₂SO₄

Molar mass: 98.079 g/mol

IUPAC ID: Sulfuric acid

Density: 1.83 g/cm³

Boiling point: 337 °C

Melting point: 10 °C

Explanation:

Mohr's salt is prepared by adding a little amount of sulfuric acid in water and then adding an equimolar mixture of hydrated ferrous sulfate and ammonium sulfate in it. Now this resulting solution mixture is subjected to crystallization. After this we get light green coloured small crystals of Mohr's salt.
