Calculate the molar solubility of pbbr2 (ksp = 4.67x10-6) in 0.10m nabr solution.

Explanation:

will dissociate into ions as follows.

Hence, for this reaction will be as follows.

We take x as the molar solubility of when we dissolve x moles of solution per liter.

Hence, ionic molarities in the saturated solution will be as follows.

                = + x

                = + 2x

So, equilibrium solubility expression will be as follows.

            =

Each sodium bromide molecule is giving one bromide ion to the solution. Therefore, one solution contains = 0.10 and there will be no lead ions. So, = 0

So, will approximately equals to .

Hence,

                        x = M

Thus, we can conclude that molar solubility of is M.

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
