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.
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.
What chemical is burning when you see a violet purple flame?
When you see a violet-purple flame, it often indicates the presence of potassium compounds, such as potassium chloride or potassium nitrate. The specific element responsible for the color is potassium.
What will you see if you dissolved bromine in water?
You will see Aqueous Bromine or Bromine water
What is the examples of solutions in chemistry?
An example of a solution in science is coffee. When for example you add sugar in coffee you can't see it because it has melted but you know its there and can taste the sweetness it gives off. Solutions are classified as something that is made up of two or more substances, but have the same apperance throughout.
What will you see when you dissolve potassium chloride with water?
Potassium chloride is soluble in water, so when you dissolve it, a colourless solution will be observed. I hope this helps!
How can you make potassium chloride precipitate?
You can make potassium chloride precipitate by adding silver nitrate (AgNO3). The chemical equation being AgNO3(aq)+ KCl(aq) = KNO3(aq) + AgCl(s) You know that silver nitrate will form a precipitate as you can see this on a solubility chart.
Ken had a beaker containing 54g of potassium chloride dissolved in 100cm3 of water at 90 degrees. he cooled the solution to 40 degrees. what would he see as the solutio cooled to 40 degrees?
As Ken cooled the potassium chloride solution from 90 degrees to 40 degrees, he would likely observe crystallization occurring. This is because the solubility of potassium chloride decreases with temperature, leading to the formation of solid crystals as the solution becomes supersaturated. He may see white crystals forming at the bottom of the beaker or floating in the solution as the solute precipitates out.

What is the metal present in potassium chloride?
It's NOT the metal as such but positive ion of the metal: Potassium, the K+ ion together with the negative chloride ion: Cl- they form the salt potassium chloride: KCl You see, it's always in the name of the salt
What happens when you add calcium chloride to potassium carbonate?
When you add calcium chloride to potassium carbonate the products will be solid calcium carbonate and aqueous potassium chloride. The chemical equation for this reaction is CaCl2(aq) + K2CO3(aq) --> 2KCl(aq) + CaCO3(s). This type of reaction is called a double replacement/displacement reaction.
Is potassium an electrolyte?
Yes Pottasium is an Electrolyte, you see a electrolyte is a mineral that that disolves in water, and carries an electric current.In your body, potassium, sodium and chloride are the electrolyte minerals. Since the body is made mostly of water, these electrolytes can be found everywhere in your body.
What salt is formed form neutralization reaction between perchloric acid and potassium hydroxide?
A hydroxide refers to the OH- polyatomic ion and is formed when an oxygen makes a covalent bond with one hydrogen (however you would not see such ions free in nature as they would more probably be in compounds). Potassium hydroxide (KOH) is formed when Potassium forms ionic bonds with OH- ions while Potassium Oxide (K2O) is formed when potassium forms ionic bonds with the Oxide (O2-) ions. Hydrochloric acid + Potassium Hydroxide ---> Potassium Chloride + Water i.e. HCl(aq) + KOH (aq) ----> KCl (aq) + H2O (l) This reaction is a neutralization reaction and occurs when an acid (HCl) reacts with a base (KOH).

What is the difference between salt and potassium chloride?
'Salt???? ' By this I think you mean 'Table Salt', which is used in food/cookery. Table Salt is sodium chloride . Potassium chloride is a CHEMICAL salt. The difference between the two is the elemental cation , sodium and potassium. Chemical Salts are of the form metal cation(M^(n+)) and acidic anion (A^(n-)). Since Table Salt (Salt) has a metal cation (N^(+) and an acidic anion (Cl^(-)), then it is also a Chemical Salt.
What are the major dissolved salts in oceans?
The Earth is composed of over 70 percent water. It is estimated that there are over 50 quadrillion tons of salt in the worldâ??s oceans.
What color do you get when you burn potassium chloride?
A lila color, from potassium spectral lines.
