Enter electrons as $e^{**}.$

Use smallest possible integer coefficients.

States are not required. If a box is not needed, leave it blank.

A $0\mathrm{.}196M$ neutral aqueous $Sc{l}_3$ solution is electrolyzed under $1$atm pressure using platinum electrodes.

$($a$)$ Write the half$-$reactions expected to occur, taking into account the effect of the non$-$standard conditions on the electrode potentials.
