Suppose 6.54g of potassium bromide is dissolved in 50.ml of a 0.70 m aqueous solution of silver nitrate. calculate the final molarity of bromide anion in the solution. you can assume the volume of the solution doesn't change when the potassium bromide is dissolved in it.

[]=0.4M

Explanation:

When you add bromide to a silver nitrate solution, silver bromide can be produced. It depends of the reactants concentration.

⇄ Kps for this reaction is , this constant indicates if the reaction can happen spontaneously or not. in this case, a small value of Kps means that precipitate can be formed.

Now we need to know if our conditions are enough to form that precipitate.

=

Due to Qsp>Ksp precipitate will be formed. notice that reaction will go on until silver has been consumed completely, silver is limiting reagent.

moles of bromide remainig =total moles of bromide-moles of bromide that reacts

moles of bromide that reacts are the same number of moles from silver beacause in reaction the mole ratio is 1:1.

b.

the accuracy of the data.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
