When doing a recrystallization what observations would prompt
Volgvan
<h2>Observation of purified crystals.</h2>

Explanation:

  • Recrystallization is the process in which a compound is dissolved in a hot solvent and then allowed to cool which forms the crystals.
  • It is a technique used for purification of solids.
  • Recrystallization mainly depends on the solubility of the solvent that means the solid should be soluble in the solvent when it is hot and should be insoluble in the same solvent when it is cool.
  • The observations while doing recrystallization is to observe the purified crystals obtained and to filter it out.

An ionic bond can be formed when one or more electrons are
xz_007 [3.2K]

Answer:

Are transferred completely from the valence shell of an element to the other

Explanation:

Basically, to form a chemical bond, you either transfer or you share. When you share, it is a case of covalent bonding which can be in several other forms. When there is a transfer, it is a case of ionic bonding.

The basic explanation for this is that while some atoms are electronically sufficient, some are electronically deficient. This means while some atoms are having an excess number of electrons, then some are having less number of electrons.

To satisfy both parties, there must be a transfer if electrons between the two parties. While the one with the excess numbers serves as the donor, the one with insufficient number of electrons serve as the acceptor
