Name, INTRODUCTION TO VOLUMETRIC GLASSWARE POST-LABORATORY QUESTIONS lts? On what do you Which of the three pieces of glassware gave the most accurate resu base your answer? 1. A laboratory procedure instructs you to deliver approximately 5 mL of water. Which piece of glassware would you select for this measurement?_ a) Buret b) Graduated cylinder c) Pipet d) Beaker 2. 3. A laboratory procedure instructs you to deliver 5.00 mL of water. Which piece of glassware would you select for this measurement? a) Buret b) Graduated cylinder c) Pipet d) Beaker 4. A laboratory procedure instructs you to deliver between 5 mL and 6 mL of water and you must know the volume of water delivered to the nearest 0.01 mL. Which piece of glassware would you select for this measurement? a) Buret b) Graduated cylinder c) Pipet d) Beaker 5. When would it be necessary to condition volumetric glassware? Explain.

Solution

1. Pipet, buret and graduated measuring cylinder can be used for volumetric analysis to gave the accurate results. Because in these three apparatus chances of error will less in comparison to rest any measuring apparatus.

2. b) graduated cylinder

in the question it is mentioned approximately so measuring cylinder can give the exact quantity without much deviation.

3. c) pipet

because it is mentioned in the quantity that 5.00mL so by measuring with pipet chances of error will be less since it can give results till +or - 0.02 mL digit accurately.

4. a) buret

because in the case of buret error chances were least in comparison to all the given options.
