From Wiktionary under the GNU Free Documentation License. In chemistry, a solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is dissolved in another substance, known as a solvent. Usually, the substance present in a greater amount is considered as the solvent. Solutions may have multiple solvents. Gases may dissolve in liquids, for example, carbon dioxide or oxygen in water. Liquids may dissolve in other liquids. Gases can combine with other gases to form mixtures, rather than solutions. All solutions are characterized by interactions between the solvent phase and solute molecules or ions that result in a net decrease in free energy. Under such a definition, gases typically cannot function as solvents, since in the gas phase interactions between molecules are minimal due to the large distances between the molecules. This lack of interaction is the reason gases can expand freely and the presence of these interactions is the reason liquids do not expand. Examples of solid solutions are alloys and certain minerals and polymers containing plasticizers. The ability of one compound to dissolve in another compound is called solubility. The physical properties of compounds such as melting point and boiling point change when other compounds are added. Together they are called colligative properties. There are several ways to quantify the amount of one compound dissolved in the other compounds collectively called concentration. Examples include molarity, mole fraction, and parts per million (ppm). Solutions should be distinguished from non-homogeneous mixtures such as colloids and suspensions. When a liquid is able to completely dissolve in another liquid the two liquids are miscible. Two substances that can never mix to form a solution are called immiscible. From Wikipedia under the
GNU Free Documentation License What is the libertarian solution to global warming? Q. OK, I'm a libertarian, and I do believe that global warming is occurring. But the vast majority of solutions I've seen proposed are either a wealth redistribution scheme (the US and other "rich" countries give loads of money to poorer, and often terrifyingly corrupt, countries so they can develop greener industries), or limit individual or corporate rights (the government taxing "bad" cars, foods, or actions to control behavior). So is there a solution to the global warming problem that doesn't involve government mucking around in people's lives, raising taxes, or restricting what companies can and can't do? Asked by Hannah B - Sat Dec 6 14:01:11 2008 - - 9 Answers - 2 Comments A. Well, a hard push towards nuclear power would be good. If people could only lose that illogical fear of nuclear power plants. France get's 80% of it's power from nuclear power, why can't the U.S.? BTW, I don't think global warming is as big of a catastrophe as it's being drummed up to be, but the fact is that we still need to advance technologically and get better sources of energy. I just don't think it is a good idea to do it based on a ridiculous hysteria that gorebull warming is.

I work in a Children's Museum where all non-washable items and surfaces are cleaned using a bleach/water solution in a spray bottle. I know that the diluted bleach solution will eventually lose its effectiveness. How long does a 20% bleach 80% water solution last and how often should it be replaced with a fresh batch? Thanks! Asked by Madeline - Wed Aug 26 14:08:55 2009 - - 2 Answers - 0 Comments A. A 10% bleach solution (90% water) is more than effective at disinfecting. I work in biological testing lab and we either use that or 70% ethanol solution to sterilize counter tops and tools. I haven't really heard of a bleach solution losing effectiveness over time so within the time frame you are using it it shouldn't be a problem as long as it is stored in a closed container (spray bottle is fine). If you are really concerned you could make it in smaller batches and use them up within a couple of months. I would say to discard it after 1 year if it hasn't been used up yet.

Q. Bottling water is a significant environmental problem. What is a solution for these companies? What can they do to solve this problem of wasting plastic and using fossil fuels to transport them? Asked by Jo - Sun Mar 18 21:36:06 2007 - - 2 Answers - 0 Comments A. much of the plastic used in the bottling process has been recycled, in fact beverage producers from beer to soda to H2O recycle more material annually than any other industry. Be sure to check the "Source" of your bottled water. It might simply be from a municipal water source and undergone additional purification... think Brita here, but only at 10,000 gallons a minute. Fossil fuels... good question... here are a few issues in regard to the logistics of providing an inexpensive product... Most loads transported by a large commercial truck from the manufacturer to the supplier weigh around 48000-5000# By carrying this much weight at one time, the bulk expense is less leaving room for some profitability.
