5. a reaction occurs between solutions of strontium bromide and silver nitrate, as shown in the equation below: srbr2 (aq) + AgNO3 (aq) → Sr(NO3)2 (aq) + AgBr (s) in collecting the precipitate, why would it be inappropriate to heat the reacted mixture and evaporate off the water?
Accepted Answer
Heating the mixture and evaporating the water would likely result in the decomposition of the silver bromide precipitate (AgBr). AgBr is known to be photosensitive and can decompose under heat, forming elemental silver and bromine gas. This would alter the composition of the precipitate and make it unsuitable for further analysis or study.
