What happens when chlorine gas is passed through lime water?
When chlorine is passed through dry slaked lime power Ca(OH)2 , bleaching powder is obtained .Slaked lime --- Ca(OH)2 Chlorine --- Cl2The chemical equn :- Ca(OH)2 + Cl2 ------> CaOCl2 + H2OCaOCl2 is bleaching powderThe three properties Of bleaching powder , (CaOCl2) areIt is a yellowish white powder with a strong smell of chlorineIt reacts with carbon dioxide , dil. HCl and di. H2SO4 to form chlorine gas.It is soluble in water but since it is generally contaminated with Ca(OH)2 , it may produce a milky solution
What happens when aqueous ammonia is added to lime water?
When aqueous ammonia is added to lime water, a white precipitate of calcium hydroxide is formed as the ammonia reacts with the calcium hydroxide present in the lime water. This reaction can be represented as: Ca(OH)2 + 2NH3 → Ca(NH2)2 + 2H2O.
When 1 liter of nitrogen gas reacts with 3 liters of hydrogen gas at constant temperature and pressure how many liters of ammonia gas will be produced?
When 1 liter of nitrogen gas reacts with 3 liters of hydrogen gas, they will react to produce 2 liters of ammonia gas. This follows the balanced chemical equation: N2 + 3H2 → 2NH3. Each mole of nitrogen reacts with 3 moles of hydrogen to produce 2 moles of ammonia.
Word equation for ammonia and water?
Ammonia reacts with water to form ammonium hydroxide.
What happens when chlorine reacts with ammonia?
When chlorine reacts with ammonia, it forms chloramine, which is a compound that is often used as a disinfectant in water treatment. This reaction is exothermic, meaning it releases heat. It is important to handle these reactions carefully due to the potential formation of toxic byproducts.
What happens when bleaching powder reacts with dil sulphuric acid?
RTYU
What happens when bleaching powder reacts with manganese dioxide?
When bleaching powder (calcium hypochlorite) reacts with manganese dioxide, it produces chlorine gas, calcium chloride, and manganese chloride. This reaction is often used in laboratory settings and industrial processes to generate chlorine gas.
What will be the products when bleaching powder reacts with carbon dioxide?
When bleaching powder reacts with carbon dioxide, calcium carbonate and chlorine gas are produced. Calcium carbonate is a white solid that can precipitate out of solution, while chlorine gas is a greenish-yellow gas with a strong odor.
Why does bleaching powder smell of chlorine in damp air?
When bleaching powder (calcium hypochlorite) is exposed to damp air, it reacts with water to release chlorine gas. This characteristic smell of chlorine gas is what you detect when using or opening a container of bleaching powder in damp conditions.
What happens to formaldehyde when it reacts with ammonia?
When formaldehyde reacts with ammonia, a condensation reaction occurs to form hexamethylenetetramine. This reaction is reversible, and the product can further react with water to release ammonia and regenerate formaldehyde.
Why bleaching powder give a typical smell in air?
it gradually looses its color.
Why do bleaching powder smell strongly like chlorine?
Bleaching powder, also known as calcium hypochlorite, releases chlorine gas when it reacts with water. The strong smell comes from this chlorine gas being released, which is reminiscent of the smell of chlorine in swimming pools.
What happens when the base ammonia is put into water?
it reacts with water. it forms OH- by reaction.
What will happen if bleaching powder reacts with dil sulfuric acid?
When Bleaching Powder is treated with excess Dil. H2SO4, Cl2 is produced. CaOCl2 + H2SO4 ----> CaSO4 + H2O + Cl2 CaOCl2 + 2HCl --------> CaCl2 + H2O + Cl2 Chlorine gas produced in this way is known as available chlorine.
What happens when ammonia reacts with Thiosulfate?
When ammonia reacts with thiosulfate, it forms an amine complex known as [N(NH3)4]+, resulting in the liberation of sulfur dioxide gas. This reaction is typically employed in qualitative analysis to detect the presence of thiosulfate ions.
What gas released when bleaching powder is added with water?
When bleaching powder (calcium hypochlorite) is added to water, it releases chlorine gas. This occurs as the compound reacts with water, producing hypochlorous acid and releasing chlorine. The reaction can be represented as follows: Ca(OCl)₂ + 2H₂O → Ca(OH)₂ + 2HOCl, where the hypochlorous acid can then decompose to release chlorine gas.
What happens when methanol reacts with ammonia?
When methanol reacts with ammonia, the primary products are methylamine and water. This reaction is typically carried out in the presence of a catalyst, such as aluminum oxide, to facilitate the conversion of methanol to methylamine. Methylamine is an important building block in the production of various chemicals and pharmaceuticals.
