What happen when chlorine gas is passed through dry slaked lime?
When chlorine gas is passed through dry slaked lime, it reacts with the calcium hydroxide in the lime to form calcium hypochlorite, which is a bleaching agent and disinfectant. This reaction also releases heat and forms calcium chloride and water as byproducts.
What happens when electricity is passed through brine?
Passing electricity through brine (saltwater solution) can result in the electrolysis of water, producing hydrogen gas at the cathode and chlorine gas at the anode. The sodium ions in the brine remain in solution. This process is used industrially to produce chlorine and sodium hydroxide.
What happens when carbon dioxide is passed through slaked lime?
When carbon dioxide is passed through slaked lime (calcium hydroxide), calcium carbonate is formed. This reaction is called carbonation and it can be used to remove carbon dioxide from gas streams in industrial processes. The calcium carbonate forms as a solid precipitate, which can be easily removed from the system.
What happens when excess Chlorine is passed through boiling toluene?
When excess chlorine is passed through boiling toluene, chlorination of the toluene molecule can occur. This reaction can lead to the introduction of chlorine atoms into the benzene ring of toluene, resulting in the formation of chlorinated derivatives of toluene. These derivatives can have different properties and reactivity compared to the original toluene molecule.
What happens when chlorine is passed through boiling toluene?
Electrophilic halogenation
What happens when chlorine gas is passed through calcium hydroxide?
When chlorine gas is passed through calcium hydroxide, it reacts to form calcium hypochlorite, calcium chloride, and water. The chemical equation for this reaction is: 2Ca(OH)2 + 2Cl2 → Ca(ClO)2 + CaCl2 + 2H2O. This is a common method used to produce calcium hypochlorite, which is commonly used as a bleaching agent and disinfectant.
What happen when chlorine gas is passed through dry slaked lime?
When chlorine gas is passed through dry slaked lime, it reacts with the calcium hydroxide in the lime to form calcium hypochlorite, which is a bleaching agent and disinfectant. This reaction also releases heat and forms calcium chloride and water as byproducts.
What happens when excess of CO2 is passed through lime vessel?
When excess CO2 is passed through a lime vessel, it reacts with the lime (CaO) to form calcium carbonate (CaCO3) through a process called carbonation. This reaction removes the excess CO2 from the system and produces calcium carbonate as a white precipitate.
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 carbon dioxide gas is passed through calcium hydroxide solution?
When carbon dioxide gas is passed/bubbled through aqueous calcium hydroxide (also known as 'limewater'), a white precipitate will be formed. This means that the solution will turn cloudy/milky due to the formation of that white precipitate.Ca(OH)2(aq) + CO2(g) → CaCO3(s) + H2O(l)The precipitate, calcium carbonate, is only sparingly soluble in water. It will exist as a suspension in the resulting solution.But when excess carbon dioxide is added, this reaction takes place instead:CaCO3(s) + H2O(l) + CO2(g) → Ca(HCO3)2(aq)The calcium carbonate undergoes further reaction with water and carbon dioxide to form calcium bicarbonate (or calcium hydrogen carbonate), which is soluble. Thus the precipitate appears to 'disappear' or 'dissolve'. Thus, a colourless solution is formed.----- Other answers -----Water is added to give calcium hydroxide, and carbon dioxide is passed through this solution to precipitate the desired calcium carbonate, referred to in the industry as precipitated calcium carbonate (PCC):if carbon dioxide is passed through it it will turn cloudy and if it is done for to long then it will turn colourless.
What does CO2 and lime water make?
When carbon dioxide reacts with lime water (calcium hydroxide solution), it forms a white precipitate of calcium carbonate. This reaction is commonly used as a test for the presence of carbon dioxide gas.
What happens when electricity is passed through brine?
Passing electricity through brine (saltwater solution) can result in the electrolysis of water, producing hydrogen gas at the cathode and chlorine gas at the anode. The sodium ions in the brine remain in solution. This process is used industrially to produce chlorine and sodium hydroxide.
What happens when electric current is passed through fused sodium chloride?
During this electrolysis are obtained chlorine and sodium.
Why does milk disappear when carbon dioxide is passed in access?
When carbon dioxide is passes into lime water (a solution of calcium hydroxide) an insoluble precipitate of calcium carbonate is produced this is composed of tiny particles that cause the milkiness.Ca(OH)2 +CO2 -> CaCO3 +H2OWhen excess carbon dioxide is passed in this produces some carbonic acid, H2CO3 that reacts with the calcium carbonate to produce soluble calcium hydrogen carbonate, (calcium bicarbonate).CO2 +H2O -> H2CO3H2CO3 + CaCO3 -> Ca(HCO3)2
What happens when carbon dioxide is passed through lime water in small amount?
A slurry of calcium carbonate is formed.
What observed when air is passed into fresh lime water through injection answer in chemistry?
Calcium hydroxide react with traces of carbon dioxide from the air, forming the white insoluble in water calciun carbonate.
What metal reacts with water to give a solution which forms a white precipitate with carbon dioxide?
Calcium. It reacts with water to form a solution of calcium hydroxide which can then react with carbon dioxide to form calcium carbonate, a white precipitate. You will get similar results with strontium and barium.
