Interpretation:
The property of liquids which accounts for meniscus at the surface in a buret is to be explained.
Concept introduction:
Adhesive forces: The forces that exist between molecules of different atoms are adhesive.
Cohesive forces: The forces that exist between molecules of same atoms are cohesive.
Answer to Problem 114A
Adhesion and cohesion forces are the reason for meniscus formed at surface in buret.
Explanation of Solution
If the force of adhesion between glass and the solution is greater than force of cohesion between the molecules of solution, meniscus is formed.
Thus, meniscus is formed due to adhesion and cohesion forces
