9 Physical Chemistry Questions and Answers:
Physical Chemistry Job Interview Questions Table of Contents:
1 :: Why silica absorb in mix bed resins in D M plant?
Because in mix bed cation & anion resin are present the removal of all ions so he absorbs at time of reamning of silica (sio2)
2 :: As per X-ray Fluorescence theory, when material particle is irradiated with X-ray the electron of innermost orbital of that element atom is exited and emits outside of the atom as photoelecrons, living behind a hole in innermost orbital . This hole is filled by outer orbital electrons. The question is that finely what happens to that photo electon which is emitted outside of the atom?
The photo electron which is emmited outside the atom will be
released in the form of heat.
released in the form of heat.
3 :: Why we are carrying standardization of karl fisher auto titrator with water and disodium tartarate?
The standardisation of karlfischer reagent is very
important before starting the experiment because the
reagent is always in contact with air and absorbs the
moisture and results in the dilution of the reagent. So it
will be better to standardise the reagent either with water
or di sodium tartarate

4 :: Today science says that clouds r formed due to sea(more than 90% sea water in cloud). but when rain starts, the rainy water is sweet while sea (salty)water is salty, how sea water is converted into sweet water?
sea water evoparates leaving salts..... so the rain water
is salt free
is salt free
5 :: What is the difference between EMF and Voltage?
emf is that force which tend to push electrons from one
poient to another . but voltage is the amount of current
passed through a given resistence.

6 :: At a constant temp. volume is inversly proportional to pressure. This is Boyles law. But, when u give pressure to a football, how the volume also increases?
Boyle's law states that" at a constant temperature the
volume of a GIVEN MASS of gas is inversely proportional to
the applied pressure.
This indicates not only the temp, but the mass must be
contstant.
But, when u apply pressure to a football, u r suplying air;
in fact u r not keeping the mass constant.
Hence Boyle's law can't be applied to this case.
Of course, when u supply only pressure from out side but
not air, definitely the volume will decrease.

1. ELEMENTAL ANALYSIS
2. FUNCTIONAL GROUP ANALYSIS
3. COLLIGATIVE PROPERTIES
4. SPECTROSCOPY

8 :: What is little silver?
platinum, its comes from spanish word Platina which means
Lttle silver
Lttle silver
9 :: Balance the following redox equations by ion electron method.
In basic medium
(i) CN- + MnO4- CNO- + MnO2
In Acidic medium
(ii) ClO3- + Cl- Cl2 + ClO2
(ii) ClO3- + 2H+ + 6Cl- ---> ClO2 + 3Cl2 + H2O
