You may know that you can also use potassium hydroxide (the more common chem. to use), also known as Lye to make biodiesel, but it is extremely hazardous for the person using it as well as the environment (if not handle appropriately). We've found that using potassium chloride, which is Potash an ingredient in fertilizers, is much safer (for both handler and the environment) and does just as good or better job of it. It's also biodegradable. It's also cheaper and easier to find.

Yes. Any CUNO water softener may use either Potassium or Sodium Chloride as a re-generant without changing settings. This is of special interest to anyone on a sodium-free or low sodium diet.

Yes. Potassium chloride can be used in place of water softener salt, though you may have to adjust the fill time. As a result more potassium chloride may have to be used than salt. Potassium chloride is generally more expensive than salt. Call 1-866-725-9662 for advice.

Yes, we do use lye in our soap making process. We use sodium hydroxide in our soaps ? All soaps (excluding detergent bars, which are totally synthetic and chemical laden) are made with lye but no lye is left in the finished soap. Our soaps are balanced so the chemical reaction has the correct amounts of both lye and oil for a balanced reaction. The result is that our soap is very close to neutral.

A.--You cannot make true soap without using lye. And here is just one of the magnificent things that happens when the lye mixes with the oils to make soap (this is called saponification). During the soapmaking process, a wonderful change takes place....glycerin is made! And once the saponification process is finished and you have soap, THE LYE NO LONGER EXISTS! This is where glycerin comes from, and just one of the many things that make homemade cold process soap so wonderful.

Potassium can also be used in the water softener. When Potassium is used however, the softener control valve will need to be adjusted. Add 3 grains to the feed water hardness setting i.e. feed water = 18 grains + 3 for potassium = 21 grains entered for the feed water setting. Also keep the level of potassium in the brine tank low.

A.--Lye (sodium hydroxide) is a very caustic substance commonly used to clear out drains from your sink, bathtub, etc. But it is crucial for making quality soaps, and when used in soapmaking, it disappears! Read on....

There is no approved cartridge to prevent overexposure of methylene chloride. The only respiratory protection adequate for methylene chloride exposure is a supplied breathing air system. Check your local Yellow Pages or the web for Safety Supply Vendors who can help provide the proper approved system.

It is advisable to check potassium levels about 2 weeks after beginning cesium, and then repeat it every two to four weeks. It is imperative that if you experience heart palpitations you have your potassium checked immediately.

Persons with known iodine sensitivity should avoid KI, as should individuals with dermatitis herpetiformis and hypocomplementemic vasculitis, extremely rare conditions associated with an increased risk of iodine hypersensitivity. Individuals with multinodular goiter, Graves' disease, and autoimmune thyroiditis should be treated with caution -- especially if dosing extends beyond a few days.

Yes: CsCl purification is essential in order to 1) remove defective particles, 2) remove condition media with its contaminants from the viral preparation, 3) concentrate the virus to a level suitable for injection and 4) resuspend the virus in a buffer suitable for injection. For in vivo work, the virus must be purified since a cell lysate contains defective particles, a large quantity of fiber and penton proteins which are known to be cytotoxic, as well as media, serum and cellular debris.

Chlorine changes the tastes and odor of water. Chlorination can also produce harmful by-products called Trihalomethanes (THMs) which are linked to incidence of cancer. No, the UV unit will use about the same amount of energy as a 60 watt light bulb. It is a cost effective, natural way to increase water quality where microbiological contamination is present and to provide peace of mind where microbiological contamination is a greater risk.

The mohel is a super-specialist, an expert at his profession, who probably possesses more experience at performing circumcisions than most doctors. A mohel may have the opportunity to perform more brisses in a month than some doctors do in an entire year. Doctors may be called away on medical emergencies and have to cancel their participation in your child's circumcision at the last minute.

When we started developing MusicXML, a DTD (Document Type Definition) was the only official W3C recommendation for defining an XML document. Since that time, XML Schemas have become an official W3C recommendation, and alternative schema languages like RELAX NG have also become available. W3C XML Schemas offer many benefits when using XML in electronic commerce and business database applications. For musical documents, though, the advantages are less compelling.

This is mainly a stylistic decision. Several XML books advise representing semantics in elements rather than attributes where possible. One advantage of doing this is that elements have structure, but attributes do not. If you find that what you are representing really has more than one part, you can create a hierarchical structure with an element. With attributes, you are limited to an unordered list.

There is another type called melt & pour soap or glycerin soap. It is generally transparent and can be quite pretty. The alcohol in the soap is responsible for the transparency. It can also cause drying. The quality is dependant on where the base was purchased. You can buy M & P at your local hobby stores but in general it very expensive and poor in quality.

Sodium hydroxide, also known as lye or caustic soda, is produced (along with chlorine and hydrogen via the chloralkali process. This involves the electrolysis of an aqueous solution of sodium chloride. The sodium hydroxide builds up at the cathode, where water is reduced to hydrogen gas and hydroxide ion.
