Mass of mohr's salt
In analytical chemistry, this salt is the preferred source of ferrous ions as the solid has a long shelf life, being resistant to oxidation. This stability extends somewhat to solutions reflecting the effect of pH on the ferrous–ferric redox couple. This oxidation occurs more readily at high pH. The ammonium ions make solutions of Mohr's salt slightly acidic, which slows this oxidation process. Sulfuric acid is commonly added to solutions to reduce oxidation to ferric iron. WebThe molecular mass of Mohr's salt, FeSO 4(NH 4) 3SO 4⋅6H 2O, is 392. Its equivalent mass is A 196 B 39.2 C 98.0 D 392 Medium Solution Verified by Toppr Correct option is D) The valence factor of mole's salt is 1. ∴Molecularmass=valencefactor×equivalentmass ∵⇒ 1392 = 392 = equivalent mass Was this answer helpful? 0 0 Similar questions
