Question

. How many moles of iodine can be obtained from 0.2 moles of potassium iodate(V)? KIO3(aq) + 5Kl(aq) + 6HCl(aq) 312(aq) + 6KCl(aq) + 3H2O(1) (4) >> ​

Answer 1

Answer:

Explanation:This is an oxidation-reduction (redox) reaction:

5 I-I - 5 e- → 5 I0 (oxidation)

IV + 5 e- → I0 (reduction)

KI is a reducing agent, KIO3 is an oxidizing agent (synproportionation (comproportionation)).

This is a precipitation reaction: I2 is the formed precipitate.
