Could some please tell me if I did these problems correctly? (I know that I did not Cancel common aqueous ions yet) Question: Write the net ionic equation for the following 1)Mixing solution of barium acetate and sodium phosphate 2)Mixing solution of thallium sulphate and magnesium chloride My answer: 1) 3Ba2+(aq)+6CH3COO –(aq)+6Na+(aq)+2PO43-(aq)=Ba3 (PO4)2(s)+6CH3COO –(aq)+2Na3+ (aq) 2) 2Ti+(aq)+SO42–(aq)+Mg2+(aq)+2Cl–(aq) =2TiCl (s)+SO4-2(aq)+Mg-2(aq) Thank you

  I thought thallium sulfate is soluble. Check that.

  I thought I put it as soluble, because I broke it up to 2Ti+(aq)and SO42–(aq. Correct me if I'm wrong. Is the rest okay?

  You have a real problem with thallium. You are using Ti and that's titanium. See Tl here. http://www.webelements.com/thallium/
