6. Consider the diagrams given in the figure below to answer the following questions. Beaker A Beaker B Beaker C Beaker D O H20 go H,o* o HCI c NAOH 0 mL NAOH Added 10 mL 20 ml 30 mL NaOH Added NaOH Added NaOH Added Why does the volume increase trom Beaker A to Beaker D . Identify the spectator ions in the illustration above. (- . .) For each beaker in the figure, determine the stage in the titration and if the solution would be acidic, basic or neutral when checked with a pH meter."

A chemist adds 215.0 mL of a 0.19M barium acetate solution to a reaction flask. Calculate the mass in grand of barium acetate the chemist has added to the flask. Round your answer to 2 sig figs.

A 623 mL NaCl solution is diluted to a volume of 1.45 L and a concentration of 4.00 M. What was the initial concentration? Express your answer with the appropriate units. • View Available Hint(s) HA M1 = 8.88 M Submit Previous Answers X Incorrect; Try Again; 4 attempts remaining Review your calculations and make sure you round to 3 significant figures in the last step.

2. How would each of the following affect your calculated molarity (too high, too low, or no effect). Explain your answers. a) The balance wasn’t zeroed with the beaker, and the beaker’s mass was included in the measurements. b) Not all of the baking soda in the final scoop that was counted actually reacted. c) The baking soda used isn’t pure sodium carbonate.
