Reaction 1: Na 2 SO 4 (aq) + BaCl 2 (aq) → BaSO 4 (s) + 2 NaCl(aq) Reaction 2: 2NH 4 OH(aq) + Na 2 SO 4 (s) → 2NaOH(aq) + 2 (NH 4 ) 2 SO 4 (aq) Reaction 3: 2HCl(aq) + Na 2 SO 4 (s) à H 2 SO 4 (aq) + 2NaCl(aq) *Reaction 4: Na 2 SO 4 (s) + Na 2 CO 3 (s) → Na 2 SO 4 (s) + NaCO 3 (s) (confused, as this shows no reaction) Also why the asterisk. I have to hunt for the asterisk. *Reaction 5: 2NaOH(s) + Na 2 SO 4 (s) → 2NaOH(s) + Na 2 SO 4 (s) (same as reaction 4) Reaction 6: 2 NaOH(aq) + H 2 SO 4 (s) → Na 2 SO 4 (aq) + 2 H 2 O(l) Results Table 1 Physical Property Test Appearance of Compound: White crystalline solid Table 2 Conductivity ( You should use page breaks to get table heading/table on one sheet) Compound Conductivity KCl Conducts electricity Na 2 SO 4 Conducts electricity NaCl

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
