Is potassium chloride saturated in dissolved in 100 g of water it is then cool down for 90C to 60C how many grams of precipitate will be form?
If the solution is saturated at 100°C and then cooled to 60°C, some of the potassium chloride will precipitate out of the solution. The exact amount that will precipitate depends on the solubility of potassium chloride at those temperatures. You would need to consult a solubility table or experimentally determine the solubility at those temperatures to calculate the amount of precipitate formed.
How do you separate water from potassium chloride solution?
Assuming you just try to get a purer gold, solve the potassium gold chloride in pure water, and slowly add a diluted solution of potassium hydroxide (caustic potash). This makes the gold precipitate out of solution as gold hydroxide. Two things that need be taken care of: first, avoid direct sunlight as it reduces the gold hydroxide to elemental metallic gold. Unless, of course, that's what you are looking after. Second, add the potash slowly, and stop as soon as you see the solution becoming a dark red, blue, violet or black (color varies depending on conditions). If you keep adding potash beyond that point, it would somewhat re-dissolve the gold hydroxide. If that happens, add a bit of diluted chlorhidric acid (ClH) to acidify the solution, and repeat the addition of potash. The dark liquid contains the gold hydroxide, but needs be left to stand for hours until all of the hydroxide falls down, and can be separated by decantation or filtration. Gold hydroxide gets easily dissolved by chlorhidric acid, if you want to make it into gold chloride.
How can you separate potassium chloride and ammonium chloride?
A mixture of ammonium chloride and potassium chloride can be separated using the process of sublimation. You must also note that both these substances are sublimable. So, the question arises that how can these substances be separated using this technique? This technique is quite feasible in this case as the sublimable temperatures of ammonium and potassium chloride differ widely. Between the two, ammonium chloride (See the related link) has lower sublimable temperatures. Therefore, it sublimes first followed by potassium chloride.
Why potassium chloride does not conduct electricity in its solid state but is a good conductor in its molten state?
In its solid state, potassium chloride consists of a regular lattice structure that does not have mobile ions necessary for conducting electricity. However, when potassium chloride is melted, the crystal structure breaks down, allowing the ions to move freely and conduct electricity.
When copper chloride breaks down what happens to the colour of the solution?
When copper chloride breaks down, the blue color of the solution fades as copper ions form a precipitate. The resulting solution will become clear or colorless as copper ions are no longer present in the solution and have formed the solid precipitate.

What is the formula for potassium cholorate breaks down into oxygen and potassium chloride?
The balanced chemical equation for the decomposition of potassium chlorate (KClO3) into oxygen (O2) and potassium chloride (KCl) is 2KClO3 -> 2KCl + 3O2. This means that for every 2 moles of KClO3, 2 moles of KCl and 3 moles of O2 are produced.
How many milligrams is 20 meq of potassium?
i believe 10 meqs of potassium is equal to 390 mg's of potassium, therefore, one meq, is equal to 39 mg's potassiumNot sure where you get your answer but according to drugs.com 10meg is equal to 750 mg of potassium20mEq of potassium chloride is 781.960 mg of elemental potassium [K], and 709.060 mg of elemental chlorine [Cl] (which is 1491.0 mg of potassium chloride [KCl]). Here's how to figure it:_________________mg = (mEq • atomic, molecular or formula weight) / valenceAtomic weight of potassium [K] is 39.0983Atomic weight of chlorine [Cl] is 35.453The molecular weight of potassium chloride [KCl] is sum of the atomic weights above: 74.551 (rounded)The valence of potassium chloride is 1Thus:(20mEq potassium chloride • 74.551) / 1 = 1491.0 mg potassium chlorideWhich breaks down to 781.960 mg of elemental potassium [K], and 709.060 mg of elemental chlorine [Cl]._________________
Why does potassium chloride conduct electricity?
Potassium chloride is an ionic solid, the ionic solids can conduct the electricity if they are in molten state or in aqueous solution.
What type of reaction is KCIO2 --- KCI plus O2?
This reaction is a decomposition reaction where a compound breaks down into simpler substances. In this case, potassium chlorite (KClO2) breaks down into potassium chloride (KCl) and oxygen gas (O2).
What happens when silver nitrate is mixed with a solution of sodium chloride?
sh*t goes down...
What kind of reaction is 2KClO3-2KCL 3O2?
The reaction shown is a decomposition reaction where potassium chlorate (KClO3) breaks down into potassium chloride (KCl) and oxygen gas (O2). This type of reaction occurs when a compound breaks down into simpler substances.
What are the electrolyes in the body?
An electrolyte is a liquid that contains ions. The body fluids such as blood, plasma and interstitial fluid has a high concentration of sodium chloride, which is broken down into sodium ion (Na+) and chloride ion (Cl-).
