Explain why benzocaine precipitates during the neutralization.

With the addition of an acid, the amine group on the benzocaine will become protonated. The protonation creates a positive charge on the benzocaine molecule. Because of this, benzocaine will become soluble in a polar solvent. However, when the solution is returned to a more basic pH level, the amine will no longer be protonated. Thus, the benzocaine will no longer be soluble and will precipitate during neutralization.

HC1 solution is mostly water. NaOH solution is mostly water. When 50mL of HC1 is mixed with 50mL of NaOH, what is the final mass

elixir [45]

Since water has a density of about 1g/mL, and we are assuming HCl and NaOH are mostly water, the total mass of the 2 solutions is 100 g.
Due to the conservation of mass, the mass of product must equal the total mass of reactant, therefore the final mass must also be 100 g.
