Cu(NO₂)₂ (aq) +K₂CO3(a) blue ppt yes FeCl3(aq) +K3 POy (aq) yellow-orange ppt yes. yes yes yes Observations (ppt., gas, etc.) 4. 3K2CO3(aq)+2FeCl3(aq) yellow ppt 5. K2CO3(aq)+2HCl (ar) gas bubbles K2CO3(aq)+H2SO4 (aq) gas bubbles 6. Did a reaction occur? 7. NaOH(aq) + HCl(aq) no visable change/ 8. 3NaOH(aq) +K3PO4 (aq) no change 9. 2NaOH(aq)+K2CO3(aq) no change 10. 2NaOH(aq) + H₂SO4 (aq) test tube got warm no visable change/ no AgNO3(aq) + HCl(aq) white ppt BAgNO3(aq) +3PO4latan ppt 13. 2 AgNO3(aq) +K2CO3 14. white ppt 2CH3COOH(aq)+K₂CO3(agas bubbles yes yes yes yes yes yes yes Note: Write molecular, total ionic, and net ionic equations for the above reactions on separate sheets of paper and turn those in with your data sheets. You will receive a zero for Experiment 10 if you do not include the pages with the equations written out. 107
As the instructions on the data sheet indicate, on separate pages (probably two or three) you need to write the molecular, total ionic, and net ionic equations for all the reactions that occurred. Make sure to include physical states and balance the equations appropriately. If no reaction occurs for a particular combination, you still need to indicate the formulas and states of the reactants. However, in these cases the reaction arrow will be followed by "N.R." If no reaction occurs, you do not need to balance the equation for that reaction or write anything for the total ionic or net ionic equations.
