Question

No. of total ions and resultant total charge in $A_2{B}_3$ electrolyte is:

• A. five and + 1
• B. five and - 1
• C. 0 and 0
• D. none of these

Answer 1

The correct option is D none of these

In writting a chemical formula of a compound, the cation (positive charge) must be written first and then anion (negative charge). In $A_2{B}_3$, if it is used as electrolyte then $2$moles of $A^{+3}$ and $3$ moles of $B^{-2}$ ions forms.

Total ${}^{\prime }{5}^{\prime }$ ions and total charge is zero $\left[2\right(3)+3(-2\left)\right]$
