Aqueous NH3 reacts with AgCl to form [Ag(NH3)2]+ complex ions, so adding NH3 dissolves the AgCl precipitate. However, Hg2Cl2 remains insoluble in the presence of NH3. This selective solubility allows for the separation of Ag+ and Hg2 2+ cations in the mixture.
Sulfuric acid is commonly added to adjust the pH of solutions, such as in industrial processes, water treatment, and laboratory experiments. It is also used in the production of chemicals like fertilizers, detergents, and explosives.
One way to distinguish between separate aqueous solutions of potassium chloride and potassium fluoride is by using silver nitrate solution. When silver nitrate is added to the solutions, a white precipitate forms in the potassium chloride solution due to the formation of silver chloride, while no precipitate will form in the potassium fluoride solution.
The hydroxide ion concentration would decrease in response to the increase in hydrogen ion concentration. This is due to the neutralization reaction that occurs between the added acid (which releases H+ ions) and the hydroxide ions (OH-) present in the solution.
One way to separate potassium chloride from aqueous potassium chloride is through evaporation. By heating the aqueous solution, the water will evaporate, leaving behind solid potassium chloride. Another method is through precipitation by adding a chemical that reacts with potassium ions to form a solid precipitate of potassium chloride that can then be filtered out from the solution.
Yes. An aqueous solution means that at least one solute is dissolved in water. You can increase the concentration by adding more solute, or you can decrease the concentration by adding more water.
When you raise the pH by adding aqueous NaOH after a precipitate forms in a solution of aqueous sodium benzoate due to a pH decrease, the precipitate likely dissolves. This is because sodium benzoate is the conjugate base of benzoic acid, so at higher pH levels, it remains in solution. The sodium benzoate will revert back to being fully soluble in its aqueous form.
The aqueous bromine will change from orange to colorless after addition of a hydrocarbon due to the formation of an organic bromide compound.
The purpose is to make it sweet.
Adding a solution of Sodium Sulphate to aqueous Barium Nitrate will produce a white precipitate of Barium Sulphate with Sodium Nitrate remaining in solution.
Aqueous NH3 reacts with AgCl to form [Ag(NH3)2]+ complex ions, so adding NH3 dissolves the AgCl precipitate. However, Hg2Cl2 remains insoluble in the presence of NH3. This selective solubility allows for the separation of Ag+ and Hg2 2+ cations in the mixture.
There are not much purpose of that.
by adding more solvent to them
Adding more solute or more solvent can change a solution.
Sulfuric acid is commonly added to adjust the pH of solutions, such as in industrial processes, water treatment, and laboratory experiments. It is also used in the production of chemicals like fertilizers, detergents, and explosives.
Adding NaCl solution to the soap mixture helps to separate the soap from the aqueous solution. This process is called salting out, where the addition of salt reduces the solubility of the soap, causing it to precipitate out of the solution.
One way to distinguish between separate aqueous solutions of potassium chloride and potassium fluoride is by using silver nitrate solution. When silver nitrate is added to the solutions, a white precipitate forms in the potassium chloride solution due to the formation of silver chloride, while no precipitate will form in the potassium fluoride solution.
