To test for insoluble matter in soap, you can perform a simple solubility test by dissolving a small amount of the soap in water and observing if any residue remains. If there is residue, filter it out and dry it to determine the amount of insoluble matter present in the soap. The percentage of insoluble matter can then be calculated by dividing the weight of the residue by the initial weight of the soap sample and expressing it as a percentage.
To prepare a soap solution for testing water hardness, dissolve a known quantity of soap in distilled water to create a concentrated soap solution. Next, dilute this concentrated solution with distilled water until it forms a lather when shaken vigorously. This diluted solution can then be used to test the hardness of water by observing how easily a lather forms when mixed with a sample of the water being tested.
A common ratio for making a soap spray for outdoor plants is 1-2 tablespoons of liquid soap per gallon of water. However, it's important to follow specific instructions on the soap product you are using as concentrations may vary. Overuse of soap can harm plants, so it's best to start with a lower concentration and test on a small area of the plant first.
I am a layman, and took Chemistry course over 40 years ago, so this answer will be temporary until a Chemist can improve it. I suspect that in the first test tube [oil and water only] that there probably will be a partial break-up of the oil and some mixing into the water, but this will be temporary until the oil seperates, floats to the surface, and partially recombines. In the case of the second test tube [oil, water, and soap] that the soap will reduce the surface tension of the oil, allowing it to break up into smaller particles, and possibly form a stable, or at least simi-stable emulsion in the water.
It isn't true, a multimeter can be used for all kinds of other measurements as well.
the "soap or detergent" act like solvents which dissolve into the water creating the water to be a cleaning solution (this was on my science test and this is the scientific term)
To test the purity of deionized water, you can use a conductivity meter to measure the electrical conductivity. The lower the conductivity, the purer the water. Additionally, you can use a Total Organic Carbon (TOC) analyzer to check for organic impurities. Conducting these tests will help determine the purity of deionized water.
Well, darling, the easiest way to tell the difference between a soapy detergent and a soapless one is to check the ingredients list. Soapy detergents contain soap, while soapless detergents use synthetic surfactants. You can also do a little test - if the detergent produces suds, it's likely soapy, but if it doesn't, it's probably soapless. Just remember, it's all about the ingredients, honey.
The method for testing water hardness that your lab in the attached link seeks to emulate is based on the use of tincture of green soap (TGS). Years ago, TGS was readily available but has been replaced by non-soap (detergent) hand cleaners. If you can locate TGS, the test proceeds by adding TGS, dropwise, to a 1 ounce sample of water and shaking between addition of drops to create suds. Either suds form or they don't. Keep adding TGS, dropwise, until you get suds. The number of drops is how you describe how hard the water is. The suds will not form until all the calcium2+ is bound up to make calcium stearate (soap scum). The less calcium2+ the softer the water. Rain water and distilled water will form suds after the addition of 1 drop of TGS because there is no calcium2+. This cannot be accomplished with non-soap detergents because detergents will form suds in soft as well as hard water because they do not form soap scum.
Dawn by far, the soap is more concentrated Not sure about today, but some years ago when there was a comparison test done, Sunlight produced the biggest, longest lasting bubbles of all dishwashing detergents of the time.
Swallowing soap will do nothing for you. Just drink water. That will help the kidneys to function better.

Natural and tap water contain varying levels of organic and inorganic substances, as well as microorganisms, that can interfere with the BOD test by contributing to the oxygen demand. Consequently, distilled or deionized water is used as a blank dilution medium, providing a consistent baseline for measuring the oxygen demand of the sample being tested.
To test soap and detergent in water, you can perform a simple experiment by adding a few drops of each into separate containers of water. Soap will create suds or foam in the water due to its ability to lower surface tension, while detergent may also create bubbles but may be more effective at cleaning oily substances. You can observe and compare the amount and quality of bubbles formed to differentiate between soap and detergent.
I believe nothing would happen to you until the salts and dirt from your hand contaminates the water making it conductive. I wouldn't want to test it and i wouldn't encourage you to. and i don't know what a edm is.

To detect a gas leak using the soapy water test, mix water with dish soap and apply the solution to the suspected area. If bubbles form, it indicates a gas leak.
