Question

Determine the molarity of the given kmno4 solution with the help of supplied m/20 mohr's salt solution by titration method ​

Answer 1

Answer is given below.

Explanation:

• Molar mass of Mohr's salt = 392 g / mol
• 1000 cm^3 of 1 M potassium permanganate require Mohr's salt of 392 g so 250 cm^3 of M / 20 potassium permanganate require Mohr's salt of  
• 392 / 20 ÷ 1000 x 250 = 4.9 g
• Molarity = moles of solute / liter of solution
• Also
• M1  x V1 = M2 x V2
• Putting the value in the above formula molarity can be calculated.
