Soapy water will hold more on a penny compared to pure water. This is because the surface tension of soapy water is lower than that of pure water, allowing it to spread out more and cover the penny's surface.
Yes, the amount of soapy water can affect how many drops fit on a penny. More soap can reduce the surface tension of the water, allowing it to spread and form a flatter shape, which may result in fewer drops fitting on the penny. Conversely, less soap increases surface tension, potentially allowing more drops to fit. Therefore, the concentration of soap in the water plays a significant role in this experiment.
When you place regular water on a penny, surface tension allows you to fit about 15-20 drops before it overflows. However, when you add soap to the water, the surface tension decreases, allowing more water to spread out rather than bead up. As a result, you can typically fit around 10-15 drops of soapy water on the penny, demonstrating the effect of soap on water's surface properties.
Yes, it is not neutral; more frequently basic.
Regular water has stronger intermolecular bonding due to its hydrogen bonding capability, which is more pronounced than in soapy water or an alcohol-water mixture. Soapy water contains surfactants that disrupt these hydrogen bonds, while an alcohol-water mixture has weaker hydrogen bonds compared to pure water due to the presence of alcohol molecules that interfere with water's cohesive forces. Therefore, regular water exhibits the strongest intermolecular bonding among the three.
soapy water does make nails rust because of the soap mixed with water are two different types of liquids which also makes it faster to rust

The heads side of a penny holds more water because it has a slightly raised edge that creates a small barrier preventing the water from spilling over the sides. The tails side is flat and the water can easily spill off the edges.

Soapy water appears frothy because of the presence of air bubbles trapped within the soap molecules. When the water is agitated or shaken, it creates more foam by incorporating more air, giving it a frothy appearance.

Because the hydrogen molecules in water want to stay connected and once you add soap it messes with the bonds and and they don't stay bonded as strongly. Also the mass and density of the water changes when you add soap.
Salt water holds more heat than fresh water
