When is it preferable to use a plastic volumetric flask instead of a glass flask?

Short Answer

Expert verified

Glass flasks have the potential to absorb tiny quantities of analyte.

Step by step solution

01

Meaning of polypropylene

Polypropylene, commonly known as polypropene, is a thermoplastic polymer with a wide range of uses. It is made from the monomer propylene through chain-growth polymerization. Polypropylene is a non-polar, partly crystalline polyolefin that belongs to the polyolefin family.

02

Explanation

It is preferable to use a plastic volumetric flask instead of a glass flask because, in glass flasks, analytes are present in trace concentrations. So, polypropylene plastic volumetric flasks are preferable over glass flasks for performing trace analysis. Glass flasks may absorb trace amounts of analyte.

A sample of ferric oxide (Fe2O3, density 5.24g/mL) obtained from ignition of a gravimetric precipitate weighed 0.2961gin the atmosphere. What is the true mass in vacuum?

What does “green chemistry” mean?

Water was drained from a buret between the 0.12- and 15.78-mLmarks. The apparent volume delivered was15.78-0.12=15.66mL. Measured in the air at22°C the mass of water delivered was15.569g. What was the true volume?

The densities (g/mL) of several substances are

:aceticacid,1.05;CCl4,1.59;S,2.07;Li,0.53;Hg,13.5;PbO2,9.4;Pb,11.4Ir,22.5.

From Figure 2-8, predict which substances will have the smallest and largest buoyancy corrections.

(a) Effect of altitude on electronic balance. If an object weighsgrams at distance ra from the center of the Earth, it will weigh mb=ma(ra2/rb2)when raised to role="math" localid="1663305908411" rb. An object weighs 100.0000g on the first floor of a building at ra=6370km. How much will it weigh on the tenth floor, which is 30mhigher?

(b) If you press the "calibrate" button of the electronic balance on the tenth floor before weighing the object, the observed mass will be 100.0000g. Why?
