How Does Oil & Dirt Get Washed Away With Soap?. Stop Complaining.
Most of the time, dirt comes in the form of grease or oil which sticks itself onto surfaces and will not come off if only water is just used. This is because oil and grease are non-polar, which means that the oil molecules are not charged and therefore are not attracted to polar substances such as water. Because of this, oil tends to stick with its own molecules or other non-polar substances.
On the other hand, water is a polar substance which is made up of one positive and one negative charge, and therefore is a fragmented substance. With this, water dissolves salt easily because salt is made up of charged ions in which the positive charge will be attracted to the negative ions in water.
Due to the fact of the nature of oil and water, you will see that oil will not dissolve in water but remain clustered on the surface. Also, oil and grease will stick onto plates and cutlery during cleaning, and no amount of water can completely remove it. That's when soap comes in. All it takes is just one layer of soap with water and the oil will be removed. How does this happen?
Well, soap is a unique substance of potassium fatty acid salts, produced through a chemical reaction called saponification. Its molecules are made up of a hydrocarbon chain, which is non-polar, as well as a carboxylate molecule which is polar. Therefore, the non-polar part of the soap - the hydrocarbon chain, is not attracted to water but to oil (lipophilic). On the other hand, the carboxylate molecules which are negatively charged, are attracted to the positively charged water molecules (hydrophilic).
In this case, when soap is applied to oil and grease, the lipophilic parts of soap will attach itself to the non polar molecules of oil. However, the other component of soap, the hydrophilic component, will be left on the surface. When water is applied onto this surface with a sponge, the hydrophilic component will be attracted to the water molecules and is lifted from the surface, together with the oil. This way, both oil and soap is removed with the wipe of the sponge. At the same time, because soap molecules have been combined with oil, other soap molecules will also be attracted to it. This is why you can see clusters of oil that are surrounded by soap within the water that has been used for washing. Of course, once soap has been used up to attract the oil, more soap would need to be added to work on the access oil.
In conclusion, our lives have been made cleaner and easier through the wonders of a simple substance called soap. Without it, we would be having a difficult time removing dirt, oil and grease in our everyday cleaning.

You don't need to a piece of paper to prove that you can do something! I don't have anything against achieving or completing degrees or obtaining masters and all that - absolutely nothing.
In fact, I am a law graduate myself and will strive to provide good educational background for my kids in the future. But I am sick and tired of people complaining about how they wish they could do something and not being qualified to do it! I mean COME ON!! Get real......
I know I sound a little harsh but you wouldn't want to know the kind of trials and tribulations that I have been through and also the kind of complaints that I have had to deal with in the past. People hoping and wishing to make some money from home, wanting to be with their children, needing to be independent, desiring more freedom, etc. And yet, they sit on their laurels and continue wishing and complaining!
Anyone can do anything they want to - the only condition is this: you want it BAD ENOUGH! You want to drive a Mercedes instead of your rundown ole pickup, go get it! If you want to live in a HUGE mansion with a swimming pool, go work for it! If you want to travel the world with your family, go save up for it! And if you want to work from home and run a business of your own, for goodness' sake, start doing something about it!
Let me give you a very simple illustration here, ok?
I am NOT a qualified graphic designer and neither have I ever taken writing lessons or search engine optimization classes or trainings or courses and whathaveyounots. None of them, whatsoever! Today, I earn a very comfortable living right from my bedroom as a graphic designer, writer, SEO copywriter and premium items designer. Assuming that it was all a fluke and that I am some sort of a special person with unique gifts. Let's also assume that God really loves me and that He was unfair to the rest the people out there still sitting there wishing they could do something about their lives.
Then how come I spent so many months money-less? How come I cried myself to sleep every single night during the first few months of being in business? How come I had to resort to begging and groveling (a little exaggeration there!) for work so that I can prove myself to the rest of the world? How come I had to fight with my family members in order to keep working from home? How come my children didn't understand me when I said I had to work? How come people look at me funny when I say I work from home? How come I feel ashamed and sometimes inferior to those people who have titles like "Chief Operating Officer" or "Head of Financial Department" or "HR Manager"....etc?
I fought really hard to get to where I am today - I can do better but what I am trying to say is that &STOP COMPLAINING!'
Experience says a lot about you, you know. In fact, I would bet all my money on the fact that people who learn things hands-on is FAR FAR better than those who got their degrees in college.
This is an experience that I would like to share with all of you. I have a client whose graphic designer went on maternity leave. So, she needed someone to do the work while she was away. I did the stuff for them, no complaints and they paid on time. However, when the graphic designer came back, she had problems with my files. At first, I thought it was my problem - that I didn't configure or save the files properly for her to continue with her work. Turns out, I had to spend a lot of time on the phone and through email teaching her how to do some basic functions using the same program that we use! The same program and yet I knew more than her? I couldn't believe it, really. She's the one with the graphic design and art degree, while I am the one with a law degree - I still have trouble understanding this. Didn't they teach those stuff to her in school or college? What in the world did she learn to do in school? And...
...thank goodness I didn't waste my time and money to get a degree! If I did, I bet you I would have regressed!
My point is this: you don't need a piece of paper to prove your abilities and worth. You need only one thing, the need, the desire, the want, the passion for it! If you think you have it, I am VERY sure you can go as far or further than those who are qualified. So, don't just sit there and whine - go do something!
