Combining Chemicals
« on: April 01, 2009, 12:56:07 AM »
I have no idea even where to begin, any help or guidance that will lead me towards solutions would be appreciated.

A 25.00 mL of 0.1255 M ferric sulfate, Fe2(SO4)3, is mixed with 70.00 mL of an 0.1400 M solution of lead nitrate, Pb(NO3)2.

Write the formulas of any precipitates expected.
Would this this one be Fe2(SO4)3 (aq) + Pb(NO3)2 (aq)  :rarrow: Fe2(NO3)2 (aq) + Pb(SO4)3 (aq)
Are these all suppose to be labeled aq??

Write the molecular equation for any reaction that may occur.

Write the complete ionic equation for any reaction that may occur.

Write the net ionic equation for any reaction that may occur.

Write the formulas of any spectator ions.

Calculate the mass of any precipitate that is formed.

Identify and calculate the concentrations for all other ions in the solution after complete precipitation has occurred. You should have at least three ion concentrations calculated. Assume that no volume change occurs on mixing these solutions.

Consult solubility table - looks like one of the products will precipitate, so it will be soild (s).

However, both formulas of your products are wrong.
