Juliette [100K]
Ions can be atomic or molecular. If an atom contains either positive or negative charge it said to be atomic cation or atomic anion.

When a molecule carry positive or negative charge it is called as polyatomic cation or polyatomic anion. Generally charged or ionized molecules are called as polyatomic ions.

In given question Fe(HCO₃)₃ ionizes as follow,

                         Fe(HCO₃)₃    →    Fe³⁺  +  3 HCO₃⁻

The Ions produced are Fe³⁺ and HCO₃⁻. Fe³⁺ is said to be atomic (Ferric) ion and HCO₃⁻ (Bicarbonate) is polyatomic ion or molecular ion.

Answer:

(A) 0.4M NaOH

Explanation:

The 20M NaOH caustic soda is diluted from 10mL to 500mL, that is:

500mL / 10mL = Is diluted 50 times.

That means we can solve the new concentration of the diluted solution dividing the stock concentration (20M) 50 times:

20M / 50 = 0.4M NaOH is the concentration of the diluted NaOH solution.

Right answer is:

<h3>(A) 0.4M NaOH</h3>
