Answer:

Solubility is a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. ... Certain substances are soluble in all proportions with a given solvent, such as ethanol in water.

The Ksp of barium fluoride, BaF2, is 1.6 x 10-6. A solution of 5.0M NaF is added dropwise to a 2.0L solution that is 0.016 M in

Hatshy [7]

Answer:

Precipitation will occur after the concentration of fluoride ions exceeds 0.01 M.

4 mL volume of NaF must be added to cause $BaF_2$ to precipitate.

Explanation:

Concentration of barium ions = $[Ba^{2+}]=0.016 M$

Volume of barium ion solution = 2.0 L

$BaF_2\rightleftharpoons Ba^{2+}+2F^-$

The solubility product of the barium fluoride = $K_{sp}=1.6\times 10^{-6}$

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

$1.6\times 10^{-6}=[0.016 M]\times [F^-]^2$

$[F^-]=0.01 M$

Precipitation will occur after the concentration of fluoride ions exceeds 0.01 M.

Concentration of fluoride ion = $C_1=0.01 M$

Volume of solution = $V_1=2.0 L$

Concentration of NaF solution added = $C_2=5.0 M$

Volume of NaF solution added = $V_2=?$

$C_1V_1=C_2V_2$

$V_2=\frac{0.01 M\times 2.0 L}{5.0 M}=0.004L$

1 L = 1000 mL

0.004 L = 0.004 × 1000 mL = 4 mL

4 mL volume of NaF must be added to cause $BaF_2$ to precipitate.

Determine the effect that hydrogen bonding has on the physical properties of water.

Andrews [41]

<span>Water can absorb high amounts of heat before there is an observed rise in temperature. It has the highest heat capacity among all liquids. This is caused by the presence of hydrogen bonding in water molecules which gives it stronger attraction between the molecules.</span>
