what is the product of AgNo(iii)+NaBr?

Answer 1

AgBr + NaNO3

Silver Bromide is insoluble, so it will precipitate out of the solution

Answer 2

Silver nitrate and sodium bromide yield sodium nitrate and silver bromide.

AgNO(3) + NaBr --> AgBr + NaNO(3)

Silver bromide precipitates during the reaction. The reaction is virtually complete under acidic conditions.

This reaction if frequently used in analytical chemistry to determine the Br- content in many compounds and is called an Argentometric titration. A standardized solution of AgNO(3) is used with a silver electrode to titrate the amount of Br- present in an unknown aqueous solution. Significant sample preparation methods may be required so the sample is in an acidic, aqueous solution.

This reaction is also frequently used to determine Cl- and I-, although I- also has redox titrations available. It is not used to determine F-, however.

Answer 3

This is the classic test for halogens.

AgNO3(aq) + NaBr(aq) = NaNO3(aq) + AgBr(s)

Silver Bromide (AgBr) precipitates out as a cream coloured solid. Everything else remains in solution.
Silver Nitrate is used to test for halogens.
Fluorides - No precipitate.
Chlorides - White precipitate
Bromides - Cream precipitate
Iodides - Yellow precipitate.
Note the subtle change of colour, as this is critical in identifying the correct halogen.
Solubility of the precipitate in ammonia solution is a further test.

Answer 4

AgNO3 + NaBr --> NaNO3 + AgBr

Answer 5

AgNO3(aq) + NaBr(aq) ===> AgBr(s) + NaNO3(aq)
