The experimental procedure in a chemical journal describes the exothermic reaction of 10.0 g
  of compound A in 25 mL of solvent with 75 mL of solution B in a 250-mL Erlenmeyer flask.
  (a) What size flask would you choose for the reaction of 500 mg of compound A? Explain.
  (b) What size flask would you choose for the reaction of 15.0 g of A? Explain.

Question 2

When HCl is emitted from a reaction mixture, why do we not simply bubble the effluent gas
  through a solution of NaOH to trap it?

Answer to Question 1

(a) With a 0.5 g reaction, the reactions isze is (0.5/10) or 0.05 times the original. Therefore, you
will need a total of 5 mL of solvent. Use a flask that is at 2X the size of the volume of sol
vent, or a 10 mL Erlenmeyer flask.
(b) The size of the reaction is 1.5X the original. Therefore, 150 mL of solvent will be needed.
This volumne can still be accommodated in the 250 mL Erlenmeyer flask.

Answer to Question 2

The dissolving HCl creates a vacuum in the gas effluent tube that will suck the sodium
hydroxide solution back into the reaction vessel.
