How do you prepare zinc chloride powder from aqueous form?
To prepare zinc chloride powder from an aqueous solution, you can first evaporate the water by heating the solution. This will leave behind the solid zinc chloride. Make sure to perform this step in a well-ventilated area as zinc chloride can release fumes. Collect the dried zinc chloride crystals for use as a powder.
Is aluminium chloride anhydrous powder an acid or alkali?
Aluminum chloride anhydrous powder is not an acid or an alkali; it is a Lewis acid. It is a compound that can accept lone pair of electrons from other molecules or ions, making it an electron-pair acceptor.
How might a scientist distinguish the compounds stronium chloride and patassium chloride?
They are both fine white powder type crystals with high Mp's so I would go with density or molar mass. The molar mass of strontium chloride is 158.53 (anhydrous, and up to 266.62g/mol at it's most hydrated) and of potassium chloride is 74.55g/mol. You could so a density test but for that you must make sure to use the anhydrous form. I believe the density of strontium chloride is 3.05g/cm3 (when it is anhydrous) and potassium chloride is 1.98g/cm3. The problem with this is if stontium chloride's density can be recorded as low as 1.93 depending on how hydrated it is so in order to this accuratedly you must use the anhydrous form.
What happens when you add iron powder to hydrochloric acid?
When iron powder is added to hydrochloric acid, a chemical reaction takes place which produces hydrogen gas and iron(II) chloride. The iron powder dissolves in the acid and the hydrogen gas is released as bubbles. The iron chloride formed remains in solution.
What green powder do you add to dilute hydrochloric acid to make copper chloride solution and carbon dioxide?
You would add powdered copper carbonate to dilute hydrochloric acid to produce copper chloride solution and carbon dioxide gas.
The appearance of anhydrous potassium chloride?
White powder like table salt
How do you make ferric chloride solution from solid ferric chloride?
In order to dissolve a solid in water, one normally breaks the solid into small pieces, preferably powder, and mixes the solute into the water. If there is some solid left over after extended mixing, the solution may have reached saturation; often, more solute may be dissolved at higher temperatures. When mixing a solution, common sense and caution should remain active at all times.
What is meant by the word anhydrous when applied to a chemical?
Anhydrous simply means 'without water'. The opposite is a hydrated substance, in which salt crystals contain water as an integral part of the crystal. For example, anhydrous cobalt(II) chloride, CoCl2, is a blue powder. Add water and you form cobalt(II) chloride hexahydrate, CoCl2.6H2O, which is a pink colour. Anhydrous cobalt chloride can be used to test for the presence of water because of this dramatic colour change. In addition, hydrated copper(II) sulfate, CuSO4.5H2O, forms bright blue crystals. Heating them drives off the water of crystallisation and anhydrous CuSO4, a grey/white powder, is formed. Adding water will reform a blue solution of the hydrated salt.

How do you prepare cupric chloride solution?
To prepare cupric chloride solution, dissolve copper chloride powder in water by stirring until fully dissolved. The concentration of the solution can be adjusted by changing the amount of copper chloride powder used relative to the volume of water. Always wear appropriate personal protective equipment and handle the chemical in a well-ventilated area.
How much potassium chloride powder you weight to obtain 4000 ppm solution?
4 g in 1 liter will give you a 4000 ppm solution.

How do you separate a mixture of ammonium chloride and chalk powder in the laboratory?
Oh, dude, separating ammonium chloride and chalk powder? Easy peasy. So, you just gotta add water to the mixture, 'cause ammonium chloride dissolves in water while chalk powder doesn't. Then you can filter out the chalk powder 'cause it won't dissolve, leaving you with the ammonium chloride solution. Like, science, man.
What makes calamine powder pink?
Zinc carbonate or zinc oxide is coloured pink with ferric oxide to make calamine powder.
What green powder do you add to dilute hydrochloric acid to make copper chloride solution and carbon dioxide?
You would add powdered copper carbonate to dilute hydrochloric acid to produce copper chloride solution and carbon dioxide gas.
