Is is possible to use sodium chloride in my potassium chloride water softener?

Potassium chloride is so expensive, I am hoping to be able to use sodium chloride instead.

Water Softener?

Tuesday, June 1st, 2010 at 1:55 am

Had the water checked 25 grains per gallon of hardness. It was considered very hard.

What I forgot to ask was what is the best salt to put in the system. It also has media guard to take out chlorine.

I have heard stuff about potassium. . . .

so is postassium chloride better than sodium chloride?

1. A liquid is thought to be pure ethanoic acid. Which of the following is the best way to test its purity?
a. measure its boiling point b.react it with ethanol c. burn it completely d. dehydrate it with concentrated sulphuric acid

2. a bottle of copper(II) oxide, an insoluable salt in water has been contaminated with some solid sodium chloride. How can the sodium cloride be removed from the copper(II) oxide?
a. place the mixture in a separating funnel b.heat the mixture and allow it to cool c. add dilute acid to the mixture and filter d. add water to the mixture and filter

3. When candle wax is heated, it softens and then melts over a range of temperatures. Which statement explains this behaviour of them wax?
a. wax is a hydrocarbon b. wax is a lubricant c. wax is an insulator d.wax is a mixture

4. How would you adapt the distillation apparatus so that a flammable liquid could be purified?

5. Write a word to describe the change that takes place when you add salt to water and stir.

6. What is the advantage of using a locating agent in paper chromatography?

How would the freezing and boiling points of distilled water and seawater compare?

A. Both the freezing and boiling points of seawater would be lower.
B. Both the freezing and boiling points of seawater would be higher.
C. The seawater freezing point would be lower and the seawater boiling point higher.
D. The seawater freezing point would be higher and the seawater boiling point lower.

Ethylene glycol is the active ingredient in most commercial automobile antifreeze. Why wouldn’t sodium chloride be used in a similar way?

A. Sodium chloride solute does not lower the freezing point of water.
B. Sodium chloride does not dissolve in water.
C. Sodium chloride lowers the freezing point of water but has other undesirable characteristics.
D. Sodium chloride is a solid while ethylene glycol is a liquid.

Thanks for your help with these!!

Water Filters

Water, especially clean and pure water is something that most of us probably take for granted. In the good old days of the distant past, most people could just drink tap water without any worries of any contamination. Nowadays, it is a completely different story. Having a good water filter for your home and for your drinking water is essential, unless, of course, you buy bottled water for all of your drinking water needs.
There is plenty to be concerned about when it comes to drinking water and the contaminants found in most tap water.
There is bacteria, strains of antibiotics, fluoride, chlorine, lead and other heavy metals and sometimes benzine and other harmful materials.
When looking at various makes and models of under the counter and counter top water filters, check to see exactly what they do and do not eliminate. Some remove only the heavy metals but do not remove other toxins that require a more sophisticated method of filtration, such as reverse osmosis.
Out of all of the water filters, there are only certain ones made for home use that actually remove all of the pathogens and chemicals such as fluoride and arsenic. Many of the other filters leave these toxins in the water even after it's been filtered.
It is very important to get the best possible water filter that will provide you with truly pure drinking water with the least amount of contamination and impurities possible.
Some refrigerators have water filters that are built right into the door. Some of these work well but most do not eliminate all of the chemicals from your water.
Personally, I prefer the Gary Null brand reverse osmosis water filter.
The Gary Null Water Filter is an advanced multimedia system. It combines the unparalleled bacteria and parasite removing performance of ceramic, with the chemical reducing ability of activated carbon, blended with a lead-eliminating media. Activated carbon removes more chlorine than any other material available on the market. For those individuals who want to eliminate fluoride from their water, the Gary Null Filter also contains a fluoride removing filter.
If you really want the best water filter for your money, this is the one to get and it's not really that expensive.
It sells for around $320.00 and the filters last about one year. The replacement cost for both filters is around $160.00 or so.
If you are looking for a cheaper way to drink purer water, you can surely afford a brita water filter, which does do quite a lot of good, but does not go as far as a more expensive and more effective water purification system.
