Describe a laboratory procedure that can be used to recover the solid solute from the aqueous solution.

Two common laboratory procedures that can be used to recover the solid solute from the aqueous solution are crystallization and evaporation.

An aqueous solution contains a solute dissolved in water. If the solute is a solid, it can be recovered by the following laboratory procedures;

To carry out crystallization, the vessel could be seeded with some crystals to aid formation of more crystals. The solution could also be cooled to enable crystallization. Sometimes, the vessel may be scratched to enable the crystals to form.

Evaporation is done using an open dish placed on a Bunsen burner. The dish containing the solution is placed on the burner and heated until the solvent completely escapes and the solid solute is recovered.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
