What mass of precipitate should be obtained by the reaction between masses of #115*g# #AgNO_3(aq)# and #85*g# of #BaCl_2# where each of the components are dissolved in water?
First we need a stoichiometric equation........
Now while nitrates, and most halides are soluble; silver chloride is as soluble as a brick, and precipitates from aqueous solution as a curdy white precipitate.
So we works out equivalent quantities of silver nitrate, and barium chloride.
And thus, because chloride is in excess, we should achieve stoichiometric precipitation of silver chloride, i.e.
And tis represents a mass of
