With 'sodium thiosulfate' (two words!) and bromine the reaction will be strong to give oxidised tetrathionate and reduced bromide: 2 S2O32−(aq) + Br2(aq) → S4O62−(aq) + 2 Br−(aq)
Bromine is an element and can't be "made" from any other element (except by a nuclear reaction). However, since the question asks for a sodium compound, one possibility is sodium bromide, which can be melted and electrolyzed to form bromine at the anode.
In iodometry sodium thiosulphate is used because it is standardized by potassium dichromate and it is the best and relaible way to standardized sodium thiosulphate using iodometric titration. Infact sodium thiosulphate is also standardized by iodimetry. The difference between both of them is only of iodine. In iodometry iodine gas is liberated that will further react with sodium thiosulphate but in iodimetry standard solution of iodine is used.
When bromine reacts with sodium thiosulfate, it undergoes a redox reaction where bromine is reduced to bromide ions and thiosulfate is oxidized to form sulfate ions. The reaction can be used to titrate bromine in solution, as thiosulfate acts as a reducing agent, consuming the bromine until all the thiosulfate is oxidized.
Starch acts as an indicator for the endpoint of the reaction between sodium thiosulphate and potassium iodate, as it forms a blue-black complex with iodine. This color change helps identify when all the iodine has been liberated from the reaction. This method is commonly used in titrations to determine the concentration of the sodium thiosulphate solution accurately.
Bromine (Br) PS if your in Mrs Timmoneys year nine class at UYSC, its a small world. -- I'm in year nine (in Australia though.) and all of the questions I need for my homework are pretty much written exactly like in the book. hahaha. Is it for science dimentions 3? haha
When bromine reacts with sodium, it forms sodium bromide. The reaction is a displacement reaction where sodium displaces bromine from its compound to form sodium bromide. The reaction is highly exothermic and produces a bright orange flame.
Yes, bromine reacts with sodium to form sodium bromide. This reaction is a displacement reaction where bromine replaces another element in a compound.
Yes: Bromine reacts with sodium to form sodium bromide.
When sodium reacts with bromine, they form sodium bromide. This is a redox reaction where sodium loses an electron to bromine, which gains an electron to form the bromide ion. The reaction is highly exothermic and can be violent if not controlled.
When sodium sulfite reacts with sulfur, it forms sodium thiosulfate. This reaction typically involves the oxidation of sodium sulfite by sulfur to produce sodium thiosulfate.
Starch indicator is added after sodium thiosulphate in iodometric titrations to help visualize the endpoint of the reaction. Starch reacts with any excess iodine produced at the endpoint, forming a dark blue-black color, allowing for easier detection of when all the thiosulphate has reacted.
The yellow color seen when sodium bromide reacts with chlorine is due to the formation of bromine, a reddish-brown liquid, which is a byproduct of the reaction. Bromine is responsible for the yellow color of the solution.
A bromine neutralizer is a chemical agent used to deactivate or stabilize residual bromine in water. This helps to prevent any excess or harmful bromine levels in water treatment processes, such as in pools or spas.
Sodium thiosulfate reacts with iodine to form sodium iodide, sodium tetrathionate, and sulfur dioxide. This reaction is often used in titrations to determine the concentration of iodine in a solution.
Bromine is an element and can't be "made" from any other element (except by a nuclear reaction). However, since the question asks for a sodium compound, one possibility is sodium bromide, which can be melted and electrolyzed to form bromine at the anode.
Sodium thiosulphate is typically white in color, appearing as a crystalline powder or solid.
In iodometry sodium thiosulphate is used because it is standardized by potassium dichromate and it is the best and relaible way to standardized sodium thiosulphate using iodometric titration. Infact sodium thiosulphate is also standardized by iodimetry. The difference between both of them is only of iodine.
