Calcium hydroxide, Ca(OH)2, is an ionic compound with a solubility product constant, Ksp, of 6.5×10–6. Calculate the solubility
kari74 [83]

Answer: The solubility of this compound in pure water is 0.012 M

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 K_{sp}

The equation for the ionization of the  is given as:

Ca(OH)_2\rightarrow Ca^{2+}+2OH^-  

By stoichiometry of the reaction:

1 mole of  Ca(OH)_2 gives 1 mole of Ca^{2+} and 2 mole of OH^-

When the solubility of  Ca(OH)_2 is S moles/liter, then the solubility of Ca^{2+}  will be S moles\liter and solubility of OH^- will be 2S moles/liter.

K_{sp}=[Ca^{2+}][OH^{-}]^2

6.5\times 10^{-6}=[S][2S]^2

S=0.012M

Thus solubility of this compound in pure water is 0.012 M

nata0808 [166]

Answer: The correct answer is C) carbon dioxide; calcium.

Explanation:

Carbonated soft drinks contain big concentrations of carbon dioxide, which is the bubbles that we see and feel. When these drinks are included regurly in the diet, the carbon dioxide levels are increased; and according to several studies high carbon dioxide values are related with bone loss.

Additionally, calcium is known for being an important nutrient for both formation and maintenance of bones, so inadequate intake of calcium in the diet results in a bone loss.
