QJEEM19Ch905c: JEE Main 2019 Chemistry - Class 12 JEEM19Ch905c Solution: A water sample has ppm level concentration of the following…

A water sample has ppm level concentration of the following metals : Fe = 0.2; Mn = 5.0; Cu = 3.0; Zn = 5.0. The metal that makes the water sample unsuitable for drinking is :

Multiple Choice Options

  • A Cu
  • B Mn
  • C Fe
  • D Zn

Step-by-Step Verified Solution

When Mn present in water with concentration 0.05 ppm or more than this then the water is unsuitable for drinking.

Here given concentration for Mn is 5.0, which is grater than 0.05 that is why it is Mn makes water unsuitable for drinking.

For other metal water is suitable for drinking when concentration for Fe = 0.2 ppm and for Cu = 3.0 ppm and for Zn = 5.0 ppm.
