Phase Diagram:
A phase diagram is a graphical representation that shows the different phases of a substance under different conditions of temperature and pressure. It provides information about the state of matter (solid, liquid, or gas) and the boundaries between these states.
Wrong Statement:
The wrong statement in the given options is option 'D', which states that a phase diagram gives information on relative concentration.
Explanation:
A phase diagram does not provide information about relative concentration. It primarily gives information about the physical state of a substance (solid, liquid, or gas) under different temperature and pressure conditions. The concentration of the substance is not directly represented on a phase diagram.
Correct Statements:
Let's analyze the other statements to understand their accuracy:
a) Gives information about concentration:
A phase diagram does not directly provide information about concentration. Concentration is a measure of the amount of a substance present in a given volume or mass. While phase diagrams may indirectly give some information about concentration changes during phase transitions, they do not explicitly depict concentration values.
b) Gives information about solubility:
Solubility refers to the ability of a substance to dissolve in a solvent. Phase diagrams do not provide direct information about solubility. However, they can provide insights into the solubility behavior of substances by indicating the temperature and pressure conditions at which different phases exist.
c) Gives information on melting and boiling points:
This statement is correct. Phase diagrams are often used to determine the melting and boiling points of substances. The phase boundary lines on a phase diagram represent the conditions at which phase transitions occur, such as the melting point (solid to liquid) and the boiling point (liquid to gas).
Therefore, the correct statements are 'b) Gives information about solubility' and 'c) Gives information on melting and boiling points'.
Select the wrong statements from the following statements with respect...
A phase diagram gives information only on the concentration of species, their solubility rate, degree of freedom and other physical properties. It does not explain about transformation rates and relative concentration (relative concentration=total concentration/equilibrium concentration).
