####49. Upon mixing lead nitrate solution with of a chromic sulphate solution, precipitation of lead sulphate takes place. How many moles of lead sulphate are formed? Also calculate the molar concentrations of species left behind in the final solution. Assume that lead sulphate is completely insoluble.
(1993, 3M)
Show Answer
Solution:
- The reaction involved is
millimol of taken
millimol of taken
Here, chromic sulphate is the limiting reagent, it will determine the amount of product.
mole produces 3 moles .
millimol will produce 7.5 millimol .
Hence, mole of precipitate formed
Also, millimol of remaining unreacted
