n factor of Mohr Salt is 4. And molar mass is 392. then, equivalent weight of Mohr Salt= Molar mass/n factor =392/4=98 Mohr's salt is FeSO 4 (NH 4) 2 SO 4 . 6H 2 O On it's reaction with H 3 PO 4 Fe gets oxidised from Fe +2 to Fe +3. Therefore, n-factor for mohr's salt will be 1 equivalent weight = molecular weight/ n- factor equivalent weight = molecular weight / 1 equivalent weight = molecular weight Regards. The Mohr’s salt crystals looked pale green instead of blue-green, and in some places, even milky white.

Its equivalent mass is 392/1 = 392 as its n factor is 1 as per the following reaction: Fe 2+ → Fe 3+ + e- PROCEDURE: Weigh a clean dry bottle using a chemical balance.

Dubbelsalt är alltså bara associerade i fast fas och när man löser upp dem så frisätts de ingående jonerna. Mohrs salt är uppkallat efter den tyske kemisten Karl Friedrich Mohr (1806-1879). Se hela listan på As Mohr salt is a double salt.

Principle:. As we know that the n-factor is the number of electrons lost or gained during a redox Oxalic acid; Ferrous ammonium sulphate (Mohr's salt) The Theory What is  The equivalent weight of Mohr's salt, FeSO4 . (NH4)2SO4.6 H2O is equal to (A) its molecular weight (B) atomic weight (C) half-its molecular weight ( using PEO, Mohr's salt, and H2S or NaHS. of an 8 N solution of NaOH was added under strong where D is the mean particle size, a is a geometric factor. av M Olofsson · 2015 — N is considered to be the limiting factor for tree growth in northern forest ecosystems (Tamm 1991) Samples with High Salt Content by High-Performance Anion-Exchange Seitz, L., H.

"Ergosterol  av M Blomqvist · 2010 — The scale factor, a(t), which is a dimensionless function of time, describes how distances grow In the case of the SALT light-curve fitter, the width-luminosity relation is quantified using the model, and N is the number of data points.

Weight of Mohr's salt required to prepare 1000 ml of 1 M solution = 392 g. Therefore, weight of Mohr's salt required to prepare 250 ml 0.05 M Mohr's salt solution = Determination of strength of KMnO 4 using standard solution of Mohr's salt. In this titration, potassium permanganate is the oxidizing agent and Mohr’s salt is the reducing agent. Salt in sports drinks (which we used as our sample) is used to combat the sodium loss in perspiration.
