A salt of KCl, potassium chloride, is dissolved in a beaker of an unknown solution. It is less soluble in the unknown solution than it is in a beaker of water at the same temperature. What explains the lack of solubility in the beaker of unknown solution?

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

if you're asking what comes out, it's steam.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
