Lecture 4 And 5

Question 1

What is potentiometry?

Answer 1

Electroanalytical technique based on emf measurement of an ec cell composed of a reference and indicator electrode

Question 2

What is a reference electrode

Answer 2

An electrode in a galvanic cell whose potential is unaffected by the properties of the solution

Question 3

What is the Indicator electrode?

Answer 3

The electrode of a galvanic cell whose potential is related to the concentration of the substance being measured

Question 4

What is the Ion selective electrode?

Answer 4

An electrode whose potential only depends on the concentration of a specific species in solution

Question 5

What are the components of a potentiometric cell?

Answer 5

Reference electrode
Indicator electrode
Salt Bridge
Analyte solution
