Why is soapy water bubbly?
When soap molecules mix with water molecules, they tend to separate out small bits of water to form bubbles. When soap mixes with water, the opposite ends of the soap molecules sandwich a thin layer of water between themselves. This creates a thin film that encompasses a tiny bit of air.

What is soap solution?
1 a cleaning or emulsifying agent made by reacting animal or vegetable fats or oils with potassium or sodium hydroxide. Soaps often contain colouring matter and perfume and act by emulsifying grease and lowering the surface tension of water, so that it more readily penetrates open materials such as textiles.
Is soapy water a homogeneous or heterogeneous?
Homogeneous mixtures occur when individual substances are uniformly distributed in a given mixture. As shown in diagram 2, soapy water is a great example. Two individual substances (water and dish soap) evenly distribute and do not separate in this homogeneous solution.
How do you separate soap and water?
One way to remove soap from water is to have it react with other substances. When the reactions occur, a solid called a precipitate is sometimes formed. A precipitate can be filtered out of the water….Soapy Water.

What is the soap molecule?
Soap molecules are composed of long chains of carbon and hydrogen atoms. At one end of the chain is a configuration of atoms which likes to be in water (hydrophilic). The other end shuns water (hydrophobic) but attaches easily to grease.
What are the soap molecules doing?
When grease or oil (non-polar hydrocarbons) are mixed with a soap- water solution, the soap molecules work as a bridge between polar water molecules and non-polar oil molecules. Since soap molecules have both properties of non-polar and polar molecules the soap can act as an emulsifier.
What does it mean to have full water in soap?
“Full water” is the idea that there is a particular water content that is a standardized “benchmark” amount for making cold process (CP) soap. Unfortunately there is no consistent definition of what this “full water” benchmark really is. Definition 1.
What does it mean to use less water when making soap?
Use the same method of handling these solutions; wear the same kinds of eye, respiratory, and hand protection; and follow the same first aid treatment. “Water discount” is the practice of using less water to make soap than the “full water” amount. You will hear soapers say, ” I did a water discount of 10% for my last batch ” or something like that.
What happens when you blow air into soapy water?
When you blow air into soapy water, the air stretches the surface. The surface tension in this stretchy layer captures the air and pulls the soapy water into the shape of a sphere. This is because a sphere has the smallest possible surface area for the volume of air it contains. The result is a soap bubble.
Why does soap and water make a bubble?
The surface tension in this stretchy layer captures the air and pulls the soapy water into the shape of a sphere. This is because a sphere has the smallest possible surface area for the volume of air it contains. The result is a soap bubble. Bubbles made from soap and water dry out and pop as the water evaporates.
