5. Some areas of the nation have limestone in the soil and lake bottoms. Explain how the presence of this mineral acts as a natu

mixer [17]

Limestone is calcium carbonate Ca(Co3) it's dissociation equation is as follows: Ca(CO3) <----> Ca+2 + CO3-2

but the solubility is very small in the presence of acid by LeChatlier's Principle you can shift to the right by adding acid

H+ + CO3-2 <-----> H+CO3- (the bicarbonate ion which is really soluble)

The system will pull more and more limestone out into solution as acid is added and neutralize the acid coming from the rain.

The solubility of BaCO3(s) in water at a certain temperature is 4.4 10–5 mol/L. Calculate the value of Ksp for BaCO3(s) at this

azamat

Answer : The value of $K_{sp}$ for $BaCO_3$ is $19.36\times 10^{-10}mole^2/L^2$ .

Solution : Given,

Solubility of $BaCO_3$ in water = $4.4\times 10^{-5}mole/L$

The barium carbonate is insoluble in water, that means when we are adding water then the result is the formation of an equilibrium reaction between the dissolved ions and undissolved solid.

The equilibrium equation is,

$BaCO_3\rightleftharpoons Ba^{2+}+CO^{2-}_3$

Initially - 0 0

At equilibrium - s s

The Solubility product will be equal to,

$K_{sp}=[Ba^{2+}][CO^{2-}_3]$

$K_{sp}=s\times s=s^2$

$[Ba^{2+}]=[CO^{2-}_3]=s=4.4\times 10^{-5}mole/L$

Now put all the given values in this expression, we get the value of solubility constant.

$K_{sp}=(4.4\times 10^{-5}mole/L)^2=19.36\times 10^{-10}mole^2/L^2$

Therefore, the value of $K_{sp}$ for $BaCO_3$ is $19.36\times 10^{-10}mole^2/L^2$ .
