Question

The surface tension of a solution obtained by dissolving soap in water is_than that of pure water

Answer 1

Explanation:

There is a common misconception that water does not have the necessary surface tension to maintain a bubble and that soap increases it, but in fact, soap decreases the pull of surface tension - typically to about a third that of plain water.

Answer 2

Answer:

Adding soap lower the water surface tension so the drop become weaker and break apart Sooner. And then the water is not pure.
