Question

1. Identify which pieces(s) of glassware could be used in the following lab scenarios.

a. Measuring 25.00 mL of a solution

b. Heating a mixture on a hot plate

c. Preparing a solution of a specific concentration

d. Slowly adding small variable volumes of solution

e. Mixing solutions

Answer 1

(a) For measuring 25.00 mL of a solution, one should use a 25.00 mL Graduated cylinder.

(b) For heating a mixture on the hot plate, one should use a beaker of appropriate volume with magnetic piece.

(c) For preparing a solution of a specific concentration, one should use a volumetric flask of appropriate volume.

(d) For slowly adding small variable volumes of solution, one should use a pipette with pump.

(e) For mixing solutions, one can use either an erlenmeyer flask or a test tube or a volumetric flask.
