A chemist wishes to prepare a pure sample of silver bromide (agbr). first the chemist combines hydrobromic acid (hbr) and silver hydroxide (agoh) in an aqueous solution. which step should be followed next?

Respuesta :

You need to boil away the water from the solution next.

Answer:

We have to heat the mixture at 100 °C or above to remove water to get pure sample.

Explanation:

The reaction between given HBr and AgOH will be:

[tex]HBr+AgOH-->AgBr(s)+H_{2}O(l)[/tex]

Now after this reaction we are getting AgBr and water as products.

To get pure HBr we have o remove water. Water can be easily removed by heating the sample at or above its boiling point, 100°C.

The steps will be

a) Filter the precipitate of HBr.

b) Dry the sample by heating it in hot air oven at or above °C.
