wt. of Mohr’s salt (g/L) = [{(7.8000 / 392.14 x V 1)/ V 2} x V 4]/V 3 x 392.14 g/L Since, V 1 = V 3 = 10ml Strength of the unknown Mohr’s salt solution = (7.8000 x V 4)/ V 2 g/L. Result: The strength of the supplied unknown strength Mohr’s salt solution was …….g/L Prepare N/20 Mohr’s salt Solution.

Salt in sports drinks (which we used as our sample) is used to combat the sodium loss in perspiration. 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.
