SO What test would you use to confirm that you have a solution of FeCl3?

I would do a reverse of the Ferric Chloride test. Take the FeCl3 solution and add a solution containing phenols in it. If red, blue, green, or purple colors form, you’ve got FeCl3.

What test would you use to identify solution of fecl3?

Ferric chloride test
The ferric chloride test is used to determine the presence of phenols in a given sample or compound (for instance natural phenols in a plant extract). Enols, hydroxamic acids, oximes, and sulfinic acids give positive results as well.

What are some ways to detect the presence of ions in solution?

The presence of an ion in a solution can be detected with a flame test. The flame test is used for detection of ions on the basis of color change. Ions undergo a color change when they come into contact with heat.

What tests can you do in the lab to identify a cation in a solution?

There are two types of tests used in chemistry to test for cations.

  • Flame Test. . The Flame test involves exposing the compound to a flame and identifying the compound by the flame color produced.
  • Sodium Hydroxide Test. .

How do the tests on known solutions containing cations?

Q1. How do the test on known solutions containing cations and anions make it possible for you to identify the cations or anions in an unknown solution? They leave a residual “solid” or change of color. You have a solution that is composed of either NaCL or CaCL₂.

What test would you use to identify a solution of FeCl3?

FeCl3 is used to indicate the presence of a phenol group by producing a purple color.

How does iron III chloride test identify phenols?

Compounds with a phenol group will form a blue, violet, purple, green, or red-brown color upon addition of aqueous ferric chloride. This reaction can be used as a test for phenol groups.

How do you identify a cation?

A cation has more protons than electrons, consequently giving it a net positive charge. For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them.

What are the preliminary tests required to identify cations in a given salt?

1. : we can identify the cation and anion in a given salt by using physical characteristics like color, taste, odor, melting point, solubility product etc.. from colors we observed : potassium dichromate, K2Cr2O7 ( orange) , potassium permanganate,KMnO4(violet), Ferric oxide, Fe3O4 (black), Ferrous sulphate , FeSO4.

What test detects Na+ ion present in a compound?

Flame test
A sample of an ionic compound produces an orange-red flame test colour. Identify the metal ion present….Flame tests.

Ion present Flame test colour
Sodium, Na + Yellow
Potassium, K + Lilac
Calcium, Ca 2+ Orange-red
Barium, Ba 2+ Green

What solution would the student use to identify the cations?

Sodium hydroxide solution can be used to identify some metal ions (cations). Solutions of aluminium, calcium and magnesium ions form white precipitates when sodium hydroxide solution is added but only the aluminium hydroxide precipitate dissolves in excess sodium hydroxide solution.

How prepared neutral fecl3?

take about 1ml of FeCl3 in test tube and add about 1ml of NH4OH. it will give red precipitate. add dilute HCl till the precipitate just dissolves. Neutral FeCl3 is prepared


Test for HBr?

To test for halide ions (Br, Cl, Fl, I) use a silver nitrate solution and then an ammonia solution. Silver nitrate solution will form a precipitate with Cl, Br, and I. Cl precipitate will be white, Br cream, and I yellow. Confirm with the ammonia solution that the AgCl dissolves into a colorless solution. AgBr will do the same but in concentrated ammonia solution. AgI is insoluble in ammonia.
