True or False; Silver nitrate reacts to determinechloride ions in water (please state why also, thanks).?

Answer 1

If chloride (or fluoride or bromide or iodide) ions are present in the water under test, then silver nitrate can be used to determine the concentration of these ions.

Reactn :

Ag+ + NO3- + M+ + X- -> AgX (ppt) + NO3- + M+

where Ag+ = silver ion
NO3- = nitrate ion
M+ = metal ion (cation) associated with halide
X- = Halide ion (Cl-, F-, Br- or I-)

The determination can be carried out in the presence of a trace of sodium dichromate which will form a light pink colour on the halide precipitate when all the halide has been precipitated.

Alternatively, you can filter the precipitate, dry and weigh it.

Answer 2

Yes

A method to determine the chloride concentration in water is to titrant it against a silver nitrate titrant. The titrant is standardized against a known potassium chloride or sodium chloride standard. The problem is that the silver waste you generate has to be disposed of and other halogens will act as interferences, depending on what's in the water.

I'm pretty sure there is a spectroscopic way to detect chloride that's more accurate.

Answer 3

the true statement is this:
silver nitrate is ionized in water, forming silver ion and nitrate ion. in silver nitrate (AgNO3) there is no chloride (Cl) so it is impossible to determine chloride ion from silver nitrate and water.

Answer 4

Sliver (I) ions react with Chloride anion to form AgCl which is really insoluble. After adding a lot of AgNO3, just fitter the precipitate and weigh it, remove the weight of the Ag+ and you have your quantity!

Answer 5

actually the correct statement is you need to electrolyze silicon dioxide and pass a charge through a patterned copper grid and hook it up to a CRT. you don't need silver ions because they don't exist in nature unless accompanied by large plasmons.

Answer 6

I THINK THAT'S THE RIGHT ANSWER.BECAUSE IT CAUSES THE WATER TO CHANGE IT'S DENSITY.
