How can we separate soap and oil from water using a decanter?

Oil float over the water surface; use a decantation funnel for separation.


Why is it that a bar of soap normally sinks but not if you put it in a soap case?

This is because the displacement of water to the the weight of the metal soap dish and soap is not equalized before the water reaches the top edges of the soap dish. If you had a deeper soap dish than it would most likely float. Also most likely the soap is 'stuck' to the dish so that is why when they sink it will not float on its own. Floating actually has to do with pressure rather than weight. For example a column of water 1 inch square and 1 foot tall, it weighs about 0.44 pounds depending on the temperature of the water so if you take a column of water 1 cm square by 1 meter tall, it weights about 100 grams. That means that a 1-foot-high column of water exerts 0.44 pounds per square inch [psi]. Similarly, a 1-meter-high column of water exerts 9,800Pa [pascals]. So it is the upward water pressure pushing on the bottom of the object that causes it to float. Each square inch (or square centimeter) of the object that is underwater has water pressure pushing it upward, and this combined pressure floats the object.


How does an egg float hypothesis?

An egg can float in salty water because the increased density of the water makes it easier for the egg to displace enough liquid to support its weight. The saltier water creates a greater buoyant force that helps keep the egg afloat.


Can a needle float in soapy water?

Yes it is not possible. Because as soap is added then surface tension would get reduced and so possibility of float becomes less. When we carefully place the same needle on ordinary water floating is quite possible as water has more surface tension


What is the pH of what is the pH of soap?

Soap, no matter how good a soap is, is soap. The pH will never change in relation to the quality of soap. It is a 'basic' pH'ed molecule (NaOH).

Does dish soap sink or float on water?

Dish soap generally floats on water due to its lower density compared to water. This is because dish soap is less dense than water, causing it to float.


Will a paper clip float on soap water?

Yes


Why does a bar of soap float in a bath tub?

A bar of soap floats in water because it is less dense than water. The air pockets and ingredients in the soap decrease its overall density, allowing it to float on the surface of the water.


Does dishsoap float on water?

Well a matter of fact, it actually does. It's because the density of dishsoap is more dense then water. :)


Does soap affect the ability of the paperclip to float?

Yes, soap can affect the ability of the paperclip to float because soap lowers the surface tension of water. When the surface tension is reduced, the paperclip may no longer be able to stay afloat and could sink.


Why does a soap dish float in a bucket of water while a cake soap sinks?

A soap dish is typically designed to float because of its shape and material composition, allowing it to stay on the surface of water. A cake of soap, on the other hand, is more dense and compact, causing it to sink when placed in water.

Why does a soap bubble float on CO2 gas?

The density of the bubble is lower.


What is added to a bar of Ivory soap that causes it to float?

Ivory soap floats because air is whipped into the soap during the production process, creating tiny air bubbles that make it less dense than water. This allows it to float instead of sinking.
