How do you prepare 4N potassium chloride?
To prepare 4N potassium chloride solution, dissolve 149.5 g of potassium chloride in 1 liter of water. This will give you a solution with a concentration of 4N. Make sure to use a balance to accurately measure the amount of potassium chloride needed.
How do you prepare stannous chloride solution in glycerol?
To prepare stannous chloride solution in glycerol, first dissolve stannous chloride in a small amount of water. Then, mix this solution with glycerol while stirring until the stannous chloride is evenly distributed. The final solution will be a stannous chloride solution in glycerol.
How you would prepare a sample of solid sodium chloride from sodium hydroxide solution and hydrochloric acid?
Add concentrated solution of Hydro chloric acid to the solution of sodium hydroxide till mixture becomes neutral (checked by litmus) then heat the mixture , when a little amount of water is left allow to cool the mixture , the crystals of sodium chloride settelted down filter and dry the crystals.
What are the apparatus needed to work with calcium chloride and water?
To work with calcium chloride and water, you will need a balance to measure the amount of calcium chloride accurately, a stir rod to mix the solution, a container to hold the mixture, and personal protective equipment such as gloves and goggles to ensure safety.
How is the completeness of separation of the benzoic acid crystals from sodium chloride known with the addition of AgNO3 solution?
Silver Nitrate solution produces a white precipitate in the presence of chloride ion. The equation is AgNO3 + Cl- ----> AgCl(s) . So if benzoic acid is completely free of sodium chloride there will be no white precipitate. You can go a stage further by weighing an aliquot of benzoic acid crystals and titrating with a known strength silver nitrate solution. By calculation you can then find just exactly how much sodium chloride is left contaminating the benzoic acid.

Is water and potassium chloride saturated solution?
Yes, a saturated solution of water and potassium chloride means that the solution contains the maximum amount of potassium chloride that can dissolve in water at a given temperature. Additional potassium chloride added to the solution would not dissolve and would remain as solid at the bottom of the container.

How many grams of crystals will b formed if a saturdayed potassium nitrate solution is cooled from 60 to 30?
The amount of crystals formed will depend on how much potassium nitrate was dissolved in the solution to begin with. As the solution cools from 60°C to 30°C, potassium nitrate will begin to crystallize out of the solution. The exact amount of crystals can be determined by calculating the solubility of potassium nitrate at 30°C and comparing it to the initial concentration in the solution.
How can you determine the chloride in soap?
If the soap is fully and completely water soluble, its chloride content can be precipitated by adding silver nitrate solution to the soap solution, and the amount of silver chloride solution used until precipitation ceases measures the content of sodium originally in the solution. There are also many other analytical methods available.
What is the concentration of chloride ion in a 2.0M solution of calcium chloride?
CaCL2 on its own cannot have a concentration. It would have to be dissolved in a solution first. Then, from the amount of CaCl2 which is dissolved in a certain amount of a solute (such as water), you would be able to figure out the concentration.
Why does potassium chloride conduct electricity in aqueous solution?
Potassium chloride dissociates into ions (K+ and Cl-) in aqueous solution, allowing for the movement of charged particles. This movement of ions enables the flow of electricity, making potassium chloride a conductor in aqueous solution.
What is the principle of chloride test?
The li mit t est for chloride is mainly used to control chloride impurity in the pharmaceutical material, depends upon the precipitation of chloride with silver nitrate in presence of nitric acid and comparison of precipitation produced in the sample with that of standard solution containing a known amount of chloride ion.
Is NaCL aq a homogenous mixture?
Yes because Sodium Chloride dissociates completely into the water as ions Any sample within the solution should measure the same amount of Na+ and Cl- and H2O
