What else can I help you with?
Can potassium chloride andsodium chloride be separated by sublimation?
No, because neither of them sublimate at 760 torr (1 atm). They melt. You could separate them by melting point, as NaCl has a melting point of 801ºC, but KCl has a melting point of 770ºC.
Why is it necessary to dry residual water with calcium chloride before distillation of tert-butyl chloride?
Drying the residual water with calcium chloride is necessary to remove any remaining moisture, which could interfere with the distillation process. Moisture can lead to incomplete reaction or formation of by-products, affecting the purity and yield of tert-butyl chloride. Calcium chloride is a common desiccant that efficiently absorbs water, ensuring a successful distillation process.
A compound colors flames violet what could it contain?
Caesium is a possibility; the flame test for caesium is said to be blue-violet, though I've never actually seen it so I'm not sure how blue or how violet it is. shitAnother possibility would be potassium, which I haveseen; it's theoretically "lilac", though if you're not an interior decorator you might equally validly describe it as "violet" or "a kind of purplish color".
What compound produces the element potassium?
Ionic compounds which contain potassium could yield potassium in a decomposition reaction; however, the energy requirements for such a reaction are very high. It can be done though: an example is the decomposition of potassium via electrolysis: 2KCl --> 2K + Cl2.
Why vital force theory is finally discarded?
The vital force theory was a theory presented by Berzelius. The 1809 theory stated that organic compounds could not be synthesized in a laboratory. The German Scientist contradicted the theory, and prepared Urea through Ammonium Chloride and Potassium Cyanate so eventually is was discarded.
How do you separate Potassium chloride from sodium chloride?
One way to separate potassium chloride from sodium chloride is through fractional crystallization. Since potassium chloride has a lower solubility than sodium chloride in water, by slowly cooling a solution containing both salts, potassium chloride will crystallize out first, allowing for physical separation. Alternatively, you could use precipitation reactions where adding a specific reagent can selectively precipitate one of the chlorides, leaving the other in solution for separation.
Does potassium and chloride combined make a covalent compound?
No. Potassium chloride is an ionic compound. (By the way, the way the question is worded implies that one could have a bottle full of "chloride," which is at least misleading.)
How would astatine react with potassium chloride?
Astatine could potentially replace the chlorine in potassium chloride to form astatine chloride and potassium. The reaction would likely be very rare and unstable due to astatine's radioactivity and scarcity.
How many grams of calcium chloride are needed to produce 10 g of potassium chloride?
To find the amount of calcium chloride needed, you would first need to determine the molar ratio between calcium chloride and potassium chloride in the chemical reaction. Then, you could use this ratio to calculate the amount of calcium chloride required to produce 10 g of potassium chloride. The molar ratio is 1:1, so the same amount of calcium chloride as potassium chloride, 10 g, would be needed.
What changes can you make to potassium chloride to make it dissolve faster in water?
You can increase the temperature of the water to help potassium chloride dissolve faster. Alternatively, you can crush the potassium chloride into smaller particles or stir the mixture more vigorously to enhance the dissolution rate.
What could the student do to the potassium chloride to make it conduct electricity?
To make potassium chloride conduct electricity, the student could dissolve it in water to create an electrolyte solution. In this solution, the potassium chloride will split into its ions (K+ and Cl-) which can carry electric current. By immersing two electrodes connected to a power source into the solution, electricity can flow through it via the movement of these ions.
Is potassium chloride used as substitute for sodium chloride?
This is a loose question. Since the most well known use for salt is in human diet, we could start an answer in this context. To replace dietary sodium chloride salt completely with potassium could well have fatal effects. Sodium chloride is essential for the function of the nervous system. However a high sodium (ion) intake can also be fatal. In the last few years, low sodium (ion) salts have been marketed. These might have as little 35% of the sodium of typical sodium chloride table salt, the substitute for the missing sodium is sometimes purely potassium chloride and sometimes potassium with some magnesium.
Could negative ion is formed when ionization occur in potassium chloride?
Cl- is formed when KCl is dissolved.
Can sodium chloride be used to make soap instead of lye?
No, sodium chloride (table salt) cannot be used to make soap instead of lye. Lye (sodium hydroxide or potassium hydroxide) is the essential ingredient needed to saponify fats and oils to make soap. Sodium chloride does not have the same chemical properties to facilitate the soap-making process.
What if potassium chlorate is contaminated with KCl?
If potassium chlorate is contaminated with KCl (potassium chloride), the mixture may still be usable but could result in impurities in the final product. The presence of KCl may affect the properties or performance of the potassium chlorate, so it is important to determine the extent of contamination before use. In some cases, the contaminated potassium chlorate may need to be purified or the amount of KCl accounted for in any reactions.
What method would be best for separating sand from a solution of potassium chloride?
One method for separating sand from a solution of potassium chloride could be filtration. The mixture can be poured through filter paper or a filter funnel, allowing the liquid potassium chloride solution to pass through while trapping the solid sand particles.
