A saturated solution of barium fluoride, BaF2BaF2, was prepared by dissolving solid BaF2BaF2 in water. The concentration of Ba2+
babunello [35]

Answer: 1.70\times 10^{-6}

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 ionization of the BaF_2 is given as:

BaF_2\rightarrow Ba^{2+}+2F^-

When the solubility of BaF_2 is S moles/liter, then the solubility of Ba^{2+}  will be S moles/liter and solubility of F^- will be 2S moles/liter.

By stoichiometry of the reaction:

1 mole of BaF_2 gives 1 mole of Ba^{2+ and 2 moles of F^-

K_{sp}=[Ba^{2+}][F^{-}]^2

K_{sp}=s\times (2s)^2

K_{sp}=4\times (7.52\times 10^{-3})^3

K_{sp}=1.70\times 10^{-6}

Thus K_{sp} for BaF_2 is 1.70\times 10^{-6}

Question 9
Shkiper50 [21]

Answer: There are 20 milliliters of 1.0 M HCl is required to be diluted to make 200 mL of a 0.1 M solution.

Explanation:

Given: M_{1} = 1.0 M,    V_{1} = ?

M_{2} = 0.1 M,    V_{2} = 200 mL

Formula used is as follows.

M_{1}V_{1} = M_{2}V_{2}

Substitute values into the above formula as follows.

M_{1}V_{1} = M_{2}V_{2}\\1.0 M \times V_{1} = 0.1 M \times 200 mL\\V_{1} = \frac{0.1 M \times 200 mL}{1.0 M}\\= 20 mL

Thus, we can conclude that there are 20 milliliters of 1.0 M HCl is required to be diluted to make 200 mL of a 0.1 M solution.
