What is a cation analysis?
It is mainly concerned with the detection of ions in an aqueous solution of the salt. There are separate procedures for detecting cations and anions, called the Cation Analysis and Anion Analysis.
How do you separate anions in a solution?
When a metal ion or a group of metal ions form insoluble salts with a particular anion, they can be separated from others by precipitation. We can also separate the anions by precipitating them with appropriate metal ions.
Which anion does the unknown solution contain?
Your unknown solution will contain 2, 3, or 4 of the following anions: chloride, carbonate, iodide and sulfate. As these ions are the ones being analyzed, they are referred to as the analytes.
How do you separate cations?
The cations of each successive group are precipitated as compounds with anions supplied by the group reagent. The precipitate (residue) containing the cations of one group are separated (usually by centrifugation). Then the group reagent for the next group is added to the remaining solution (centrifugate).
How will you separate mixture of metal and nonmetal?
Answer. Answer: in separation with an eddy-current separator, external magnetic fields induce eddy currents in the conducting particles in the powder mixture and they are then affected by the magnetic fields to repel the metal particles which hence are knocked off and separated from the non conducting resin particles.
How a magnet can be used to separate mixture?
Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. Due to the magnets, magnetic particles are being drifted by the movement of the drums. This can create a magnetic concentrate (e.g. an ore concentrate).
What are the different components of the mixture?
A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions and colloids.
Which one of the following techniques would best be used to separate soil and water?
Answer. Answer: Soil and water can be separated by decantation.
