What happens when the gas obtained by heating sal ammoniac and slaked lime is allowed to pass through excess of chlorine?

Ans- When excess of ammonia reacts with chlorine, it gives ammonium chloride and nitrogen gas and when ammonia reacts with excess of chlorine, nitrogen trichloride and ammonium chloride is obtained.

What happens when ammonium chloride reacts with slaked lime?

-When ammonium chloride reacts with slaked lime or calcium hydroxide, ammonia gas is evolved with its characteristic pungent odour. Calcium hydroxide is a stronger base and thus displaces ammonia which is a weaker base from the ammonium chloride salt.

What happens when calcium hydroxide and ammonium sulphate is heated?

When calcium hydroxide is heated with ammonium chloride crystal. A colourless pungent smelling basic gas i.e, ammonia is obtained. With an excess of NH4OH, the ppt. dissolves to give a colourless solution of tetraamine zinc(II)sulphate.

What is the formula of sal ammoniac?

NH4ClAmmonium chloride / Formula

What happens when slaked lime is heated?

Slaked lime reacts with chlorine gas to produce the bleaching agent calcium hypochlorite – a common form of ‘swimming pool’ chlorine. When heated with coke, a form of carbon, calcium oxide combines to form calcium carbide.

Which gas is obtained by heating slaked lime and ammonium chloride?

Ammonium chloride is yielded as a by-product in the ammonia-soda process for making sodium carbonate. It also is produced by reaction of ammonium sulfate and sodium chloride solutions. When mixed with slaked lime (calcium carbonate), ammonia gas is the result.

What happens when ammonium chloride is treated with caoh2?

ii) Calcium Hydroxide reacts with ammonium chloride to give ammonia according to the equation. Ca(OH)2 + 2 NH4Cl –> CaCl2 + 2NH3 + 2H20. the volume at STP of ammonia liberated at the same time.

What is slaked lime in chemistry?

Calcium hydroxide, also called slaked lime, Ca(OH)2, is obtained by the action of water on calcium oxide. When mixed with water, a small proportion of it dissolves, forming a solution known as limewater, the rest remaining as a suspension called milk of lime.

What does sal ammoniac do?

Uses. It is commonly used to clean the soldering iron in the soldering of stained-glass windows.

What is a sal ammoniac block?

Sal Ammoniac, also called a tinning block, quickly cleans any carbon build-up that collects on the tip of a soldering iron. Simply rub the tip of a hot iron against the block and in seconds, the tip is clean, bright and hot.

What happens when slaked lime is left in atmosphere?

When exposed to the atmosphere this calcium hydroxide can react again by absorbing carbon dioxide from the atmosphere to once again become calcium carbonate.
