What happen when you add iodide to silver nitrate?
If you add iodide (iodine ions) to Acidfied Silver Nitrate, a pale yellow precipitate is formed. This precipitate is Silver Iodide (AgI).
How can you detect the presence of the SO4-2?
Firstly add some AgNO3. You should see that no precipitate forms. If it forms a precipitate, it is not a SO42-.Then add some BaCl2 - If there are SO42- ions a white precipitate will form.
How do you differentiate between nitric acid and hydrochloric acid?
Add AgNO3 solution. If a white precipitate (AgCl), it's HCl. If no precipitate, HNO3.
Will calcium chloride and potassium phosphate precipitate?
yes it will precipitate DNA if your lysing nuclei; add benzamidine hydrochloride though as a protease inhibitor.
How neutral fecl3 solution prepare?
Take 1 ml FeCl3 solution. add ammonia solution drop wise till brown precipitate just form. Now again add FeCl3 solution till brown precipitate just dissolve. This is your Neutral FeCl3 solution.

How can distingished sodium chloride from sodium iodide?
Take a few drops of both samples and add some lead nitrate. A yellow precipitate indicates lead iodide and it gives the inference that it contains iodide ions, hence the solution of sodium iodide.
Will calcium chloride and potassium phosphate precipitate?
yes it will precipitate DNA if your lysing nuclei; add benzamidine hydrochloride though as a protease inhibitor.

How do you identify lead II chloride?
Add the compound to nitric acid untill the solution is near colourless, then following this add 2-3 drops of silver nitrate, if a white precipitate forms then the chloride ion is present. to identify if the Cation is lead, try doing a flame test with an emission spectra. cl- + ag+ ---> AgCl

What is the purpose and procedure for digesting the precipitate?
Usually, what you're doing is to add a reagent (acid or base, for example) so that the precipitate redissolves. That allows you to run further tests.
What is the test for hydrogen iodide?
Add silver nitrate. If it is present it forms a yellow precipitate
How do you test for halide ions?
If you wish to test for the presence of halogen in an iodoform, then you must first inject the iodoform with a touch of helium. This helium will make the halogen react and change colors, making it notable in the iodoform.
Describe the test for aluminium ions?
Test: Add aqueus sodium carbonate solution, then warm it. Observation: Formation of white precipitate. Deduction: The presence of aluminum ions, Al3+ Or Test: Observation: Add aqueous sodium hydroxide White precipitate occur Add aqueous sodium hydroxide (excess) & warm White precipitate solute Test with red litmus paper Changes red - blue Deduction: The presence of aluminum ions, Al3+
How do you precipitate fluoride from water?
Add silver nitrate solution. flouride is precipitated as silver fluoride
