Question

Explain the effect of presence of impurities on the surface tension of liquid.

Answer 1

Oxidation directly affects surface tension. As surface tension increases, intermolecular forces increase. ... The Presence of ImpuritiesThe presence of impurities on the surface of, or dissolved in, a substance directly affects the surface tension of the liquid.

Answer 2

Hey dear,

# Effect on impurities on surface tension -

- Surface tension is the property of a liquid surface to act as stretched elastic membrane.

- Effect of an impurity on surface tension of liquid depends upon its solubility.

# For soluble impurities -

- Addition of soluble impurities to liquid increases its surface tension.

# For insoluble impurities -

- Addition of insoluble impurities to liquid decreases its surface tension.

Hope this was helpful. Thanks dear.
