In order to deter-mine constancy in the distribution factor, the per-centage of solid carrier was varied in all the expenments.

In most physical activities where the length could be longer than two hours, or results in heavy sweating, 450 mg of sodium or more within the sports drink is recommended to maintain plasma volume and plasma sodium levels.

Result: The strength of the supplied unknown strength Mohr’s salt solution was …….g/L Molar mass of Mohr’s salt is 392gmol-1. It is a primary standard. Since, 1000cm 3 of 1M potassium permanganate require Mohr’s salt of =392g So, 250cm 3 of M/20 potassium permanganate require Mohr’s salt of = \[\frac{\frac{392}{20}}{1000}\times 250\] = 4.9g. Accurately weigh 4.9g of Mohr’s salt using a chemical balance and watch glass 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.

Mohr's salt is - FeSO 4 . (NH 4) 2 SO 4 .6H 2 O. In Mohr's salt Fe is in +2 state (Fe 2+) , it oxidises by removing 1 electron and converts to Fe 3+. Therefore n- factor = 1. ( 1 electron is removed per mole of Mohr's salt). Mohrs salt är ett s.k. dubbelsalt, d.v.s. det innehåller tre joner som samkristalliserat till en stabil fast fas.
