Question

Which compound produces the greatest number of ions when 1 mole is dissolved in water?
A aluminium sulfate
B ammonium carbonate
C ammonium nitrate
D calcium nitrate

Answer 1

Explanation:

Ammonium nitrate is a chemical compound with the chemical formula NH4NO3. It is a white crystalline solid consisting of ions of ammonium and nitrate. It is highly soluble in water and hygroscopic as a solid, although it does not form hydrates. It is predominantly used in agriculture as a high-nitrogen fertilizer.

Answer 2

Answer:

When 1 mole of aluminum sulfate is dissolved in water, it produces the most ions, i.e. option (A).

Explanation:

Let us consider that complete ionization will take place of the compounds when dissolved in water.

(A) Aluminium sulfate-Al₂(SO)₄)₃. Its ionization will be as follows,

$Al_2(SO_4)_3\rightarrow 2Al^+^3+3SO_4^-^2$

The ionization of aluminum sulfate will create a total of 5 ions.

(B)Ammonium carbonate-(NH₄)CO₃.It will be ionized in the following manner:

$(NH_4)_2CO_3\rightarrow 2NH_4^++CO_3^-^2$

The ionization of Ammonium carbonate will create a total of three ions.

(c)Ammonium nitrate-NH₄NO₃.It will be ionized in the following manner:$NH_4NO_3\rightarrow NH_4^++NO_3^-^3$

The ionization of ammonium nitrate will create a total of two ions.

(D)Calcium nitrate-Ca(NO₃)₂.It will be ionized in the following manner:$Ca(NO_3)_2\rightarrow Ca^+^2+2NO_3^-^1$

The ionization of calcium nitrate will create a total of three ions.

Hence, when 1 mole of aluminum sulfate is dissolved in water, it produces the most ions, i.e. option (A).
