Physical Chemistry Interview Questions

 
1.
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
2.
What is little silver?
3.
What are the different by which a new molecule can be characterized?
4.
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?
5.
What is the difference between EMF and Voltage?
6.
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?
7.
Why we are carrying standardization of karl fisher auto titrator with water and disodium tartarate?
8.
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?
