What is the colour of barium chloride solution?
A solution of barium chloride is added to a solution of potassium chromate, a yellow precipitate forms.
What is the valency of barium chloride ion?
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.
Name a salt which gives white precipitate on ammonium hydroxide solution and is insoluble in excess?
One such salt would be aluminum chloride since it is soluble but when reacted with ammonium hydroxide, the insoluble aluminum hydroxide forms a precipitate. Not sure what is meant by "is insoluble in excess", however.
What salt gives flames green color?
Barium salts, such as barium chloride or barium nitrate, are commonly used to produce a green flame when burned. The green color is a result of the specific wavelength of light emitted by the barium ions during the combustion process.
How many grams of barium chloride are needed to make 20 mL of a 2m solution?
To prepare a 2 m solution of barium chloride (BaCl₂), you need to know the molarity (moles per liter) and the molecular weight of BaCl₂, which is approximately 208.23 g/mol. For a 2 m solution, you need 2 moles per kilogram of solvent. Since 20 mL is 0.02 kg, you would need 0.04 moles of BaCl₂ (2 moles/kg × 0.02 kg). Multiplying 0.04 moles by the molar mass (208.23 g/mol) gives approximately 8.33 grams of barium chloride.
What is the colour of barium chloride solution?
A solution of barium chloride is added to a solution of potassium chromate, a yellow precipitate forms.
What is the precipitate color of silver nitrate and barium chloride?
Silver chloride (AgCl) gives a white precipitate. Silver Bromide (AgBr) also gives a white precipitate, though it's a slightly more creamy white than the precipitate formed by AgCl. Silver iodide (AgI) gives a pale yellow precipitate.
How many chlorines are used to form barium?
Barium gives its two electrons to two chlorine atoms (to form chloride ions) and they form an ionic compound barium chloride.
What is the test for barium ions?
The test for barium ions involves adding a solution of a sulfate compound (e.g. sodium sulfate) to a solution containing the barium ions. A white precipitate of barium sulfate forms if barium ions are present.
Reaction of aluminum sulfate with barium chloride?
The balanced chemical equation for Barium chloride plus Aluminium sulphate gives Barium sulphate Aluminium chloride is represented as .3BaCl2(aq) + Al2(SO4)3(aq) --> 3BaSO4(ppt) + 2AlCl3(aq).The ppt formed are white in color.
What is the valency of barium chloride ion?
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.
What does AgNO3 and NaCl gives?
When silver nitrate (AgNO3) is mixed with sodium chloride (NaCl), a white precipitate of silver chloride (AgCl) is formed. This reaction is a double displacement reaction where the silver cation from AgNO3 and the chloride anion from NaCl switch partners to form the insoluble AgCl precipitate.
Which anion gives white precipitate with silver nitrate?
Chloride anions form a white precipitate of silver chloride when mixed in solution with silver nitrate.
What precipitate will be formed when sodium acetate will be added with hydrochloric acid?
When sodium acetate is added to hydrochloric acid, the resulting precipitate will be sodium chloride. This is due to the reaction between the sodium ions from sodium acetate and the chloride ions from hydrochloric acid.
Which reactant ion gives white precipitate with AgNO3 and light red when treated first with HCL then KSCN?
The reactant ion is likely to be Chloride (Cl-) ions. With AgNO3, Cl- ions form a white precipitate of silver chloride (AgCl). When treated with HCl followed by KSCN, the white precipitate of AgCl dissolves in HCl to form a colorless solution, then reacts with KSCN to form a light red color due to the formation of silver thiocyanate (AgSCN).
What is the formula for a barium chloride solution reacts with sodium sulfate solution to produce solid barium sulfate and sodium chloride in a solution?
The III is there because as a transition metal, iron can have multiple oxidation states. This means iron is 3+. The charge on each Cl is -1, so you need 3. This gives you FeCl3 Next, Barium has 2+ charge, so you need two OH-'s i.e. Ba(OH)2
Which compound give brown precipitate with alkaline potassium per mangnate solution?
Ferrous chloride in presence of hydrochloric acid gives brown precipitates of Ferric chloride with potassium permanganate.
