What sodium compound makes bromine?
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.
What is the use of Sodium thiosulphate in iodometry?
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.
Reaction of bromine with sodium thiosulfate?
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.
Why do you use starch to standardise sodium thiosulphate using potassium iodate?
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.
What is a compound of sodium and bromine?
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
What happens when bromine reacts with sodium?
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.
Does bromine react to sodium?
Yes, bromine reacts with sodium to form sodium bromide. This reaction is a displacement reaction where bromine replaces another element in a compound.
Does bromine react with soduim?
Yes: Bromine reacts with sodium to form sodium bromide.
What is the reaction of sodium and bromine?
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.
What is the reaction of sodium sulphite and sulphur?
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.
Why is starch indicator added after sodium thiosulphate?
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.
Why does when sodiumbromide reacts with chlorine the solution turns yellow?
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.
What is a bromine neutralizer?
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.
What is the reaction between sodium thiosulphate and iodine?
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.
What sodium compound makes bromine?

What color is Sodium Thiosulphate?
Sodium thiosulphate is typically white in color, appearing as a crystalline powder or solid.
