Question

Identify the monoatomic and polyatomic ions from the following equation-
$Pb(N{O}_3{)}_2$ + $K_{2}S{O}_4$ $\to$ $2KN{O}_3$ + $PbS{O}_4$

• A. Sodium hydroxide + calcium bromide = Calcium hydroxide + sodium bromide; calcium; 1
• B. Sodium hydroxide + calcium bromide $\to$ Calcium hydroxide + sodium bromide; calcium; 2
• C. Sodium hydroxide + calcium bromide $\leftrightarrow$ Calcium hydroxide + sodium bromide; calcium; 2
• D. Sodium hydroxide + calcium bromide $\to$ Calcium hydroxide + sodium bromide; potassium; 2

Answer 1

The correct option is B

Sodium hydroxide + calcium bromide $\to$ Calcium hydroxide + sodium bromide; calcium; 2

Monoatomic ions- Ions consisting of only one atom.
Polyatomic ions- Ions consisting of two or more types of atoms.

In the given equation, $P{b}^{+2}$ and $K^{+}$ are the monoatomic ions and ${\mathrm{NO}}_3^{-}$and ${\mathrm{SO}}_4^{-2}$are the polyatomic ions.
