Pre-Laboratory Assignment 1. (1) Briefly explain the hazards associated with each of the solutions used in this experiment. (4) total ionic equation and net ionic equation 3. Equation 8 describes the reaction that occurs when a barium chloride solution (BaCly) is mixed with Bac04(s) + 2 NaCl(aq) (Eq. 8) (1) Write the total ionic equation for this reaction. why it is essential that you wash your hands with soap or detergont after finishing this experiment, before leaving the laboratory a sodium oxalate solution (Na C2O BacHaq) + Na2C2O4(aq) â 2. Briefly distinguish between the following pairs of terms as they pertain to this experiment (2) Write the net ionic equation for this reaction. (1) filtration and filtrate (3) Calculate the theoretical yield in moles of barium oxalate (BaC20) formed if 1 1.00 mL of 8.25 Ã 10 2M BaCl2 solution were mixed with 10.00 mL of 9.35 Ã 10-2M Na2C04 solution. (2) filtrate and residue (3) molecular equation and total ionic equation(4) Calculate the molar mass of BaC20
