A simple qualitative test is the flame test: barium has a pale/apple green color.
The name for this ion is:barium ion
A barium ion is denoted as Ba^2+.
Barium forms a +2 charge, along with all other group 2 metals.
The valency of a barium ion is +2. Barium chloride (BaCl2) consists of a barium ion (Ba^2+) and two chloride ions (Cl^-), which gives the overall compound a neutral charge.
The chemical formula for barium perxenate is Ba2O8Xe. It is composed of one barium ion (Ba2+) and one perxenate ion (XeO4^2-).
When barium hydroxide solution is mixed with sulfuric acid, a white precipitate of barium sulfate is formed due to a double displacement reaction. Barium sulfate is insoluble in water and thus forms a solid precipitate. This reaction is used in chemistry labs to test for the presence of sulfate ions.
The name for this ion is:barium ion
Barium ion = Ba2+ Hydroxide ion = OH-
Barium chloride; BaCl2
A barium ion is denoted as Ba^2+.
barium ion is a cation. rest listed are anions.
The barium ion has a charge of +2. It loses two electrons to become positively charged.
A cation is a positively charged ion. Barium ion is Ba^2+, chloride ion is Cl^-, nitrate ion is NO3^-, and chromate ion is CrO4^2-.
Barium ion = Ba2+ Hydroxide ion = OH- The compound they make is Barium hydroxide = Ba(OH)2which is a precipitate insoluble in water.
The silver nitrate test provides a negative result on the presence of a chloride ion because silver chloride is insoluble in water and forms a white precipitate when silver ions react with chloride ions. This precipitate masks the presence of the chloride ion in the test solution, giving a negative result.
The sulfate ion is precipitated with barium chloride.The presence of sodium can be tested by flame photometry.
When barium ion is added to a hydroxide ion, the two opposite charges attract each other to form barium hydroxide Ba2+ + OH------>Ba(OH)2.
