24. Consider the following equations:
Equation 1:
2 ClO3^−(aq)+I2(aq)→Cl2(aq)+2 IO3^−(aq)
Equation 2:
Cl2(aq)+2 NaOH(aq)→NaCl(aq)+NaClO(aq)+H2O(l)
Which statements about these reactions is/are notnot correct?
I.Iodine is reduced in equation 1
II.Chlorine is reduced only in equation 1
III. Chlorine is oxidized and reduced in equation 2
B
Explanation:
In equation 1, the oxidation state of Cl decreases from +5 to 0 (reduced), and the oxidation state of Iodine increases from 0 to +5 ( oxidized).
In equation 2, the oxidation state of Cl increases from 0 to +1 in NaClO (oxidized), and also decreases from 0 to -1 in NaCl (reduced).
