uh kay,tis is chemistry..tell me the easiest way to prepare for the insoluble salt??

The easiest way to prepare an insoluble salt is to produce it from two aqueous solutions each containing an ion present in the salt!\n\nSo, you'll just mix two solutions, and the insoluble salt appears! Of course, if you intend to prepare a certain amount/ mass of the salt, you may need to carry out some calculations to determine the necessary concentrations/ volumes of the 2 initial solutions. \n\nYou'll also get another product in the reaction, but it should be soluble and will not contaminate the desired product (the insoluble salt).  \n\nYou may refer to this website to gain a better understanding...\nhttp://www.wpbschoolhouse.btinternet.co.uk/page01/AqueousChem/AqueousChem.htm#salts [Refer to point (4)]

b a solution, the salt will dissolve

Na+ and OH- you are dissolving a salt\n\nby the way, i am getting a phd in chem, so trust me. also, there are tons of answers in there that are totally bullshit.

Adding sulphuric acid and sodium hydroxide respectively??

There are all sorts of salts:\nacid + base = salt + water\nHCl + NaOH = NaCl + H2O\n\nNaCl is sodium chloride. This is the same stuff we use at the table. If you have a look at the packet it came in you will probably find there are a few other things in the 'table salt' too - perhaps some iodides and an anti-caking agent to keep it running freely.\n\nMore info. on 'table salts':

mix it...let NaCl dissolve in water...then let the mmixture evaporate or perhaps bring the mixture into a boil 'til you can see the formation of crystals...   try it... i've encountered such experiment in my chemistry class... im not quite certain of the procedures though...it's two years ago...cant remember it well...^_^

iodized salt or baking soda

salt water DOESNT WORK...alum..its like a seasoning kinda u can get it at almost any grocery store (a white powder) just dab a bit on it and wash ur hands really good cuz u dont want to get it in ur eyes and keep ur mouth open for it to dry on and it will be gone in a few days (unless they are really bad then a week or so?)

Best method if practical is to freeze it.\nIf not sealed within a steralized container.

sodium & chlorine to make NaCl, table salt

boil water and add teaspoon of salt, pour into container and refrigerate for a day\npour out and wash container\nsmell should be done

uncles a chemist, melt it HELLA HOT, ones more dense than other so if its in a tube one will go to the top and one will go to the bottem, then go for it. good luck\nemail me for problems hjrboy7896@hotmail.com

I think that isolating potassium is the wrong approach.  Potassium metal reacts with atmospheric water to form KOH and hydrogen gas.  If you accidentally get water on the metal the reaction is so vigourous that the metal will catch fire, which will be dangerous.  \n\nTry a different approach.  Dissolve KCl in water and add a molar equivalence of Silver iodide, AgI, also dissolved in water..  AgCl is nearly insoluble in water (~0.9 mg/L at 10C)  and will precipitate out, leaving KI in solution.  Filter out the AgCl and evaporate the water, leaving solid KI.  \n\nThe two biggest problems starting with KNO3 are:  It will be nearly impossible to salt out the nitrate because of its high solubility in salt form, and two, many nitrate salts, particularlyof metals, are highly explosive and dangerous.  KCl is cheap and plentiful, so why not just buy some?

Sea salt melts it quickly.\n\n\nPeace

Drop Mg or Zn or something like that in HCl.  Or use electrolysis on water, but that's a lot harder.

You know, I answered exactly the same question not 2 days ago.\n\nAnhydrous copper sulfate and water would be the easiest two. \n\nYou can buy copper sulfate at any good garden supply shop and most larger hardware stores. The copper sulfate usually sold is hydrated, and is already blue in colour.\n\nYou can make it anhydrous by putting it the oven, uncovered on a sheet of tin foil at 160oC or hotter. You will know when it has become anhydrous beause it goes white. This is quite safe to do in your kitchen oven, all you are doing is driving off the water. No nasty fumes or residues are produced.\n\nStore the crystals in an airtight jar to stop them absorbing water from the air. When you are ready add some water to a few crystals they will retrun to their original blue colour.\n\nThe other possibility is to manufacture your own cabbage indicator. That will make a bluish purple colour when mixed with baking soda. I've included a link with instruction on how to do this.

to what? Table salt? Morton Lite, half sodium, half potassium chloride
