Question

Potassium nitrate is shaken with water truly and the mixture so obtained is allowed to pass through the filter paper cone. Will you get any residue?

Answer 1

Answer:

$\mathrm{Potassium}\mathrm{salt}\left({\mathrm{KNO}}_3\right)$:

$\mathrm{Potassium}\mathrm{salt}\left({\mathrm{KNO}}_3\right)$ is a soluble ionic compound.

• It will dissociate completely in an aqueous solution to form potassium cations$\left({\mathrm{K}}^{+}\right)$, and nitrate anions,$\left(N{O_3}^{-}\right)$.
• $$\begin{gathered} {\mathrm{KNO}}_3\left(\mathrm{aq}\right)\to {\mathrm{K}}^{+}\left(\mathrm{aq}\right)+{\mathrm{NO}}_3^{-}\left(\mathrm{aq}\right) \\ \mathrm{Potassium}\mathrm{Potassium}\mathrm{Nitrate} \\ \mathrm{nitrate} \end{gathered}$$
• $\mathrm{Potassium}\mathrm{salt}\left({\mathrm{KNO}}_3\right)$ will dissolve in water and form a true solution in water.
• We will not get any residue on passing through the filter paper cone

Conclusion:

Therefore, We will not get any residue when the Potassium nitrate and water mixture passes the filter paper cone.
