What are the two ways to prepare ammonium sulphate?
The two common ways to prepare ammonium sulphate are neutralizing ammonia gas with sulfuric acid or reacting ammonium hydroxide with sulfuric acid. In the first method, ammonia gas is bubbled through sulfuric acid to form ammonium sulphate. In the second method, ammonium hydroxide is slowly added to sulfuric acid to produce ammonium sulphate.
What mass of calcium chloride is needed to prepare 2.000 L of a 2.25 M solution?
To calculate the mass of calcium chloride (CaCl₂) needed to prepare a 2.000 L solution at a concentration of 2.25 M, first determine the number of moles required: ( \text{moles} = \text{Molarity} \times \text{Volume} = 2.25 , \text{mol/L} \times 2.000 , \text{L} = 4.50 , \text{mol} ). The molar mass of calcium chloride is approximately 110.98 g/mol, so the mass needed is ( 4.50 , \text{mol} \times 110.98 , \text{g/mol} \approx 497.41 , \text{g} ). Therefore, you would need approximately 497.41 grams of calcium chloride to prepare the solution.
How do you prepare 0.05M calcium chloride?
To prepare a 0.05 M calcium chloride (CaCl₂) solution, first calculate the required mass of CaCl₂ by using its molar mass, which is approximately 110.98 g/mol. For 1 liter of a 0.05 M solution, dissolve 5.55 grams of anhydrous CaCl₂ in distilled water. Add the calcium chloride to a volumetric flask, then fill the flask with distilled water up to the 1-liter mark. Mix thoroughly to ensure the solute is fully dissolved.
What uses nitric acid making paper making paint or making fertilizers?
Nitric acid is largely used to prepare ammonium and calcium nitrate, common fertilizers for agriculture.
How do prepare hard water?
To prepare hard water, simply dissolve calcium and magnesium salts like calcium chloride or magnesium sulfate in regular water. The concentration of these salts determines the hardness of the water. The dissolved salts will increase the mineral content of the water, making it hard.
How do you prepare ammonium chloride?
Mix ammonia with a solution of hydrochloric acid, then evaporate the solution. The remaining salt is what you want.
How can a solution of ammonia be used to prepare ammonia sulphate?
A solution of ammonia can be used to prepare ammoniumsulfate by reacting it with a solution of sulfuric acid to produce a solution of ammonium sulfate, which can be dried if desired to prepare solid ammonium sulfate.
How to prepare ammonium in the school laboratory?
To prepare ammonium hydroxide in a school laboratory, mix ammonia gas with water in a suitable container. Ammonia gas can be generated by adding a strong base, such as sodium hydroxide, to ammonium chloride solution. The resulting solution will contain ammonium hydroxide, which can be used for various experiments. Always ensure proper safety measures and follow laboratory protocols when handling these chemicals.
What are the two ways to prepare ammonium sulphate?

In the first method, ammonia gas is bubbled through sulfuric acid to form ammonium sulphate. In the second method, ammonium hydroxide is slowly added to sulfuric acid to produce ammonium sulphate.
How do you make buffer solution of ammonium chloride and ammonium hydroxide of pH 10?
To prepare a buffer solution of pH 10 using ammonium chloride and ammonium hydroxide, you would mix the two solutions in a specific ratio determined by their pKa values. The concentrations of ammonium chloride and ammonium hydroxide should be carefully calculated to achieve the desired pH. It is important to use a pH meter to verify the pH of the buffer solution and make adjustments if necessary.
How do you prepare HgNH2Cl?
To prepare HgNH2Cl, first dissolve mercury(II) chloride (HgCl2) in water. Then add aqueous ammonia (NH3) to the solution until a white precipitate of mercury(II) amine chloride (HgNH2Cl) forms. The precipitate can be filtered and washed to isolate the compound.
How do you a prepare ferric alum indicator?
To prepare ferric alum indicator, dissolve 5-10 grams of ferric ammonium sulfate in 100 ml of distilled water. This solution will serve as the indicator for chloride ions, turning yellow in the presence of chloride ions.
How do you prepare ammonium fertilizer?
the ammonium salt produced by a neutralization process, by reacting the ammonium hydroxide with dilute sulphuric acid. the amount of ammonia added into the sulphuric acid is enough when the amniotic smell produced. drop the ammonia little by little. then, heat while stir the mixture until the solution becomes 1/3 of the original volume. lastly, to obtain the salt, the filtration process should be done after the solution is cool.

How do you prepare a pure sample of dry carbonate using solution of ammonium carbonate?
To prepare a pure sample of dry carbonate using a solution of ammonium carbonate, you would need to first evaporate the solution to dryness to obtain solid ammonium carbonate. Then, heat the solid in a crucible to decompose it into ammonia, carbon dioxide, and water. Finally, collect the carbon dioxide gas and purify it to obtain the pure dry carbonate.
