Consider the following reaction equation:
SO42-(aq) + 2H+(aq) + ye– \(\to\) SO42-(aq) + H2O(1).

The value of y in the equation is

  • 2 checkmark
  • 3
  • 4
  • 6

The correct answer is: A

Explanation

from the reaction, the total charge on the left side = The total charge on the right side

-2 + 2 + y = -2 : y = -2 : y = 2
