What is the molar solubility of pbbr2 in 0.500 m kbr solution?

The molar solubility of PbBr₂ in 0.500 KBr solution is 2.64 × 10⁻⁵ M

PbBr₂ is an ionic compound that dissociates in water to produce lead ions and Bromine ions.

The dissociation reaction can be expressed  as:

The solubility product constant can be written as:

If  

where;

In a 0.500 kBr solution;

Assuming that x = 0; since it is too small than 0.500

∴

x = 2.64 × 10⁻⁵ M

Therefore, we can conclude that the molar solubility of PbBr₂ in 0.500 KBr solution is 2.64 × 10⁻⁵ M

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
