The hcl solution, naoh solution, acid #1 solution and juice #2 solution are all clear, transparent and odorless. The phenolphthalein solution is clear as well but has a little odor. While the acidic solution mixed with naoh, the solution remains transparent at the beginning then a last drop of naoh added that makes the titration reach the equivalence point; the solution turns to light pink. The pink color becomes darker once the color of solution changed. For part 1, the dilute naoh solution doesn"t have physical changes as concentrated.
