Step-by-step solution

Aqueous solutions

Aqueous solutions are those in which water serves as the solvent. The majority of ionic solids are water soluble. They divide into their ions when dissolved in water and disperse uniformly across the solution. When two distinct ionic chemicals' aqueous solutions are combined, they produce a highly fast reaction since they were already separated (as ions).

Disassociation of barium nitrate

a)

Let’s write the reaction for disassociation of barium nitrate,

$\mathrm{Ba}{\left({\mathrm{NO}}_3\right)}_2\left(\mathrm{aq}\right)\to {\mathrm{Ba}}^{2+}\left(\mathrm{aq}\right)+2{\mathrm{NO}}_3^{-}\left(\mathrm{aq}\right)$

We can see that there should be twice as many ions with a charge of -1 in the solution as there should be ions with a charge of +2.(iv) is the image that corresponds to our data.

Barium nitrate in aqueous solution is shown below

Disassociation of sodium chloride

b)

Let’s write the reaction for disassociation of sodium chloride,

$\mathrm{NaCl}\left(\mathrm{aq}\right)\to {\mathrm{Na}}^{+}\left(\mathrm{aq}\right)+{\mathrm{Cl}}^{-}\left(\mathrm{aq}\right)$

We can see that there should be same asnumber of ions with a charge of -1 in the solution as there should be ions with a charge of +1.(ii)is the image that corresponds to our data.

Sodium chloride in aqueous solution is shown below

Disassociation of potassium carbonate

c)

Let’s write the reaction for disassociation of potassium carbonate,

${\mathrm{K}}_2{\mathrm{CO}}_3\left(\mathrm{aq}\right)\to 2{\mathrm{K}}^{+}\left(\mathrm{aq}\right)+{\mathrm{CO}}_3^{2-}\left(\mathrm{aq}\right)$

We can see that there should behalf the ionswith a charge of -2 in the solution as there should be ions with acharge of +1.(iii)is the image that corresponds to our data.

Potassium carbonate in aqueous solution is shown below,

Dissociation of magnesium sulfate

d)

Let’s write the reaction for disassociation of magnesium sulfate,

${\mathrm{MgSO}}_4\left(\mathrm{aq}\right)\to {\mathrm{Mg}}^{2+}\left(\mathrm{aq}\right)+{\mathrm{SO}}_4^{2-}\left(\mathrm{aq}\right)$

We can see that there should be same as number of ions with a charge of -2 in the solution as there should be ions with a charge of +2.(i)is the image that corresponds to our data.

Magnesium sulfate in aqueous solution is shown below,

Therefore

a) Barium nitrate matches to figure (iv)

b) Sodium chloride matches to figure (ii)

c) Potassium carbonate matches to figure (iii)

d) Magnesium sulfate matches to figure (i)
