Question

Q.2 Answer the following questions
i) Write any two functions of a salt bridge
ii) What is the Oxidation state of S in H2 S206 ?
iii) How many moles of acetic anhyelride will
pentaacetate from I mole of glucose
iv) What is an isolated System
v) What type of intermolecular force leads to high d
vi) Write probable electronic configuration of chrom
vii) The vapour pressure of pure water at 25 0 C is 1​

Answer 1

Answer:

Explanation:

i)  Salt bridge prevents the diffusion or mechanical flow of solution from one-half cell to another. It prevents or minimizes the liquid-liquid junction potential. (Potential arises between two solutions when they are in contact with each other). Salt bridge acts as an electrical contact between two half cells.

ii) +2.5

The oxidation state +2.5 is just the average oxidation state for the S atom.

iii)  How many moles of acetic anhydride will be required to form glucose pentaacetate from 1 mole of glucose? Solution : 10 moles of acetic anhydride.

Answer 2

Answer:

(1) Salt bridge prevents the diffusion or mechanical flow of solution from one-half cell to another. It prevents or minimizes the liquid-liquid junction potential. (Potential arises between two solutions when they are in contact with each other). Salt bridge acts as an electrical contact between two half cells.
