Question

The valence state of Tc99m is usually reduced when preparing kits through the use of:

a. Nitrate
b. oxygen
c. stannous ions
d. alumina

Answer 1

The valence state of Tc99m is usually reduced when preparing kits through the use of stannous ions.

Step-by-step explanation:

The valence state of Tc99m is usually reduced when preparing kits through the use of stannous ions. In the reduction half-reaction, stannous ions are oxidized, while Tc99m is reduced. This reduction leads to the formation of the desired kits.
