  • Question 6
    1 / -0

    Water contains 88.89% of A by weight is decomposed into its elements B and oxygen. Pure C is a poor conductor of electricity and hence it is acidified using dilute sulphuric acid. When electric current is passed through acidulated water, using platinum electrones, hydrogen gas is evolved at cathode and oxygen gas is evolved at D.

    What is D?

  • Question 7
