Question

how is neutral ferric chloride solution prepared​

Answer 1

Answer:

It requires the use of neutralized iron(III) chloride solution normally just prior to running the test. This is done as older solutions of iron(III) chloride that have been exposed to air may not be neutral due to the absorption of carbon dioxide into the aqueous solution, thus changing the pH slightly more acidic.
