Chapter 4, Problem 1Q

Interpretation Introduction

Interpretation:

The type of glassware that would be most appropriate for reaction of $75\text{ mg}$ reactant A with $95\text{ mg}$ the reagent in $2\text{ mL}$ should be determined. Also, the type of glassware that would be most appropriate for reaction of $0.80\text{ mg}$ reactant A in $20\text{ mL}$ of solvent should be determined.

Concept introduction:

Laboratory glasswares are the types of equipment that are made up of glass and are utilized for scientific work in the laboratories. The glassware is used in the laboratories because of their low coefficient of expansion and high resistance to chemical attack. Ground glass joints are one of the types of glassware utilized in laboratories to easily fit into leak-tight apparatus from commonly available parts.

Microscale and miniscale glassware are two important types of glassware used for the reaction that use a small amount of the reactants.

Explanation of Solution

The microscale glassware is the glassware used for the reactions that use very small amounts of material nearly $10\text{ mg}$. Microscale glassware is designed to minimize the surface area and to eliminate the transfer of tiny amounts of substances from one container to another. While miniscale glassware is used for the reaction use a small amount of the material nearly $1\text{ gram}$ .

Therefore, the reaction of the $75\text{ mg}$ of reactant with $95\text{ mg}$ of reagent that takes place in 2 mL solvent should use the microscale glassware like standard taper or Williamson glassware.

The reaction of $0.80\text{ mg}$ reactant A in 20 mL solvent should occur in miniscale glassware and that is miniscale standard taper glassware.
