G[mcquarrie 22-7] the value of ksp for pbcro4(s) in equilibrium with water at 25◦c is 2.8 · 10−13m2 . write the chemical equation that represents the solubility equilibrium for pbcro4(s) and calculate its solubility in grams per liter in water at 25◦c.

Answer :

The solubility equilibrium reaction will be:

The  solubility in grams per liter in water at is,

Explanation :

The solubility equilibrium reaction will be:

Let the solubility be 's'.

The expression for solubility constant for this reaction will be,

Given:

Solubility constant = =

Now put all the given values in the above expression, we get:

Now we have to convert the solubility in gram per liter.

Solubility =

Solubility =

Solubility =

Therefore, the solubility in grams per liter in water at is,

the answer would be a

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
