A salt has the formula AB2, and a Ksp value of 4.3 × 10-7. What is the solubility of the salt? A. 6.5 × 10-3 Molar B. 4.8 × 10-4 Molar C. 4.8 × 10-3 Molar D. 7.5 × 10-3 Molar

The solubility of the salt is

Explanation:

Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as

The equation for the reaction will be as follows:

By Stoichiometry,

1 mole of gives 1 mole of and 2 moles of

Thus if solubility of is s moles/liter, solubility of  is s moles\liter and solubility of is 2s moles/liter

Therefore,  

The solubility of the salt is

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
