2. A student was given five known solutions and asked to study their interactions. The solutions were 0.1 M Na SO, 0.1 M NaCl, 0.1 M Ba(NO), 0.5 M HCl, and 0.3 M Na₂CO₂. a. To determine the behavior of these solutions, the student mixed them systemically in pairs and used the grid below to record the observations. Based on your lab data and observations, fill in the grid, indicating what observations the student would have made when each pair of solutions was mixed. Use "N.R." to indicate no reaction, "ppt" for precipitate (or sollid) formed, and "gas" for a released gas. solutions NaCl HCI Na CO Ba(NO₂) Na 50₁ NaCO HCI Naci solutions E D C b. The student was then given the same set of five solutions, but this time in test tubes labeled A, B, C, D, and E. When these solutions were mixed, the student recorded the following observations. A A N.R. N.R. white ppt. N. R. N.R. N.R. N.R. Na 50 с white ppt. N.R. D gas Ba(NO₂) Using the information from part 2a, identify the solution in each test tube.

Question

Transcribed Image Text:2. A student was given five known solutions and asked to study their interactions. The
solutions were 0.1 M Na SO, 0.1 M NaCl, 0.1 M Ba(NO₂), 0.5 M HCl, and 0.3 M Na₂CO₂-
a. To determine the behavior of these solutions, the student mixed them systemically in pairs
and used the grid below to record the observations. Based on your lab data and
observations, fill in the grid, indicating what observations the student would have made
when each pair of solutions was mixed. Use "N.R." to indicate no reaction, "ppt" for
precipitate (or solid) formed, and "gas" for a released gas.
