Question Q143) Assertion : Total charge on NA ions of CO32- is 1.93 × 105 coulomb.
Reason: Charge on one electron in 96500 coulomb



SOLUTION

As one CO3-2 ion have two unit charge
∴ 1 mole of CO3-2 ion havee charge
= 2 × 96500 C = 1.93 × 105 C
Charge on one mole electron = 1.602 × 10-19× 6.022 × 1023
=96478 = 96500 C
Answer : (c)
