What is SOAP?
At Vermont Soap Organics we take oils, which make you greasy, and turn them into soap, which make you clean. This process is called saponification (making soap). Soap is fascinating stuff. It is actually a salt that foams! This crystalline nature of soap allows it to be made clear as glass when boiled in alcohol with sugars. Now a salt is what you get when you mix an acid and a base together. The acids and bases neutralize each other and a salt forms in the process. Soap, is made from acidic oils and an alkaline solution. Think of it like a child’s seesaw. Oil and alkali must be in balance to make the perfect bar of soap. Any unsaponified oils are called “Free fatty acids”, and they add to the moisturizing effect of high quality soaps. Use too much, and the soap will not lather, and it will have a shortened shelf life. Excess alkali, or “Free Alkali” is harsh and drying to sensitive skin. About 25% of us are estimated to get a dry skin reaction to free alkali in our soaps. At Vermont S
Barbara Daiker Brookwood Junior High 201 East Glenwood-Lansing Road Glenwood, IL 60425 708-758-5252 Objectives: The student will: 1. Observe soap-making in order to learn this process 2. Discover how soap behaves through experimentation 3. Develop a model of a soap molecule from observations 4. Apply information learned to soap’s uses Materials needed: Soap making Soap/Food Coloring Soap/Grease 15 grams lard petri dishes transparent jars 50 mL NaOH (6M) milk with lids 5 grams NaCl food coloring water (300 mL) 500 mL beaker toothpicks oil (5 mL) watch glass liquid soap liquid soap (5 mL) hot plate stirrer (homemade soap solution) liquid detergent homemade soap chips water (homemade soap) Strategy: 1. SOAP-MAKING is both dangerous and time-consuming. Therefore soap should be prepared as a DEMONSTRATION as follows: Place the beaker on a hot plate and add the lard. When the lard is almost melted, add the NaOH. You will notice the layers are immiscible at the start. Place a watch glass on t
SOAP is an XML-based messaging protocol. It defines a set of rules for structuring messages that can be used for simple one-way messaging but is particularly useful for performing RPC-style (Remote Procedure Call) request-response dialogues. It is not tied to any particular transport protocol though HTTP is popular. Nor is it tied to any particular operating system or programming language so theoretically the clients and servers in these dialogues can be running on any platform and written in any language as long as they can formulate and understand SOAP messages. As such it is an important building block for developing distributed applications that exploit functionality published as services over an intranet or the internet. Let’s look at an example. Imagine you have a very simple corporate database that holds a table specifying employee reference number, name and telephone number. You want to offer a service that enables other systems in your company to do a lookup on this data. The
