Question

Certain gram equivalents of an ion is reduced to the element when it absorbs 6 × 1022 electrons. The number of equivalents of the ion is (A) 0.1 (B) 0.01 (C) 0.001 (D) 0.0001

Tardigrade Admin · Accepted Answer

6 × 1023 electrons reduce 1 g eq. of the ion ∴ 6 × 1022 electrons reduce =(6 × 1022/6 × 1023)=0.1 g eq. of the ion.

$6 \times 1 0^{23}$ electrons reduce $1 g$ eq. of the ion

$∴ 6 \times 1 0^{22}$ electrons reduce $= \frac{6 \times 1 0 ^{22}}{6 \times 1 0 ^{23}} = 0.1 g$ eq. of the ion.
