Which of the following is the best piece of laboratory glassware for preparing 500.0 mL of an aqueous solution of a solid?

(A) Volumetric flask
(B) Erlenmeyer flask
(C) Test tube
(D) Graduated beaker
(E) Graduated cylinder

Respuesta :

Answer:

The correct answer is option A.

Explanation:

Volumetric flask  : A glass ware with round lower body with flat bottom and with thin cylindrical neck along with mark which indicates the specific volume filled to that mark.It is used in preparation of standard solution of compound with desired concentration with fixed volume.

Erlenmeyer flask : is a flask with conical shape with flat bottom used in titration  experiments to carry out reaction with fixed volume of solution.

Test tube : Small cylindrical tube with rounded bottom used to observe reaction in between reactant taken in small amount.

Graduated beaker : Laboratory glassware used measure larger volumes of solution or to mix or stir solutions and liquids.

Graduated cylinder : Laboratory thin cylindrical glassware with accurate marking of volume used to measure an accurate volume of solutions or liquids required in an experiment.

Volumetric flask is the best piece of laboratory glassware for preparing 500.0 mL of an aqueous solution of a solid

The best laboratory glassware that can be considered to measure 500.0 mL of an aqueous solution of a solid is A: Volumetric flask.

  • Measuring equipment are items that are required in determining the quantity of substance we need in the laboratory.

  • Option, B,C,D are also measuring equipment but, since Volumetric flask is in the question, it serves as one that is best fit to measure 500 ml of aqueous solution of a solid.

  • Volumetric flask which is a laboratory apparatus is graduated and it is used in measuring standard solutions.

Therefore, option A is correct.
