Why does the addition of HCl dissolve such insoluble salts as BaCrO4 and CaC2O4?
1. a. For BaCrO4 with HCl identifying acidic and basic salts. what significant base is present inside BaCrO4? b. For CaC2O4 with HCl identifying acidic and basic salts. what significant base Is present inside CaC2O4? Alkaline Earths + Alkali Metals GROUP 4 Ba2+ Ca2+ NH Nat [flame test (NaOH] [HC₂H₂02] [Might smell Yellow flame* [K₂CrO4] NH3, but wait] CONF. Nat BaCrO4(s) *px on all three: DI water, to see minimum amount of yellow Your solution 0. 2m NaCl, to see...
Why are Ca2+ salts generally insoluble compared to Group IA and ammonium salts?
"Hard" water contains mainly salts of Ca2+ and Mg2+, both of which form many insoluble salts. You have a water sample and need to determine whether it contains Ca2+ and/or Mg2+. When you add ammonia to the solution, followed by ammonium chloride and ammonium oxalate, a white precipitate of CaC2O4 should form if Ca2+ is present. What is the purpose of adding the ammonium chloride to the reactant mixture? a. The chloride ion helps to form the calcium chloride precipitate....
Does Cu(s) dissolve in HCl?
Why does Ph3CO-MgBr+ dissolve when HCl is added? Write a chemical equation to describe what happens. Does it dissolve in the water layer or the ether layer? Is the final product, tripehnylmethanol, soluble in ether or water? Explain your answer. Please Please answer everything what question is asking and explain answers thoroughly. Thank you.
1-Luminol is insoluble in water, BUT it does dissolve in aqueous NaOH. Explain. 2-Discuss the mechanism for the chemiluminescence of luminol.
Charcoal does not dissolve In either water or soluble in liquid CS_2. Sulfur does not dissolve in water, but is soluble in liquid CS_2. Potassium nitrate dissolves in water, but is insoluble in liquid CS_2. Outline a procedure for separating the three substances.
In terms of Le Chatelier's principle, explain how the addition of ammonia causes the highly insoluble AgCl (a group I salt) to dissolve.
a) Using the appropriate equations show why addition of 6M HCl to a saturated KCl solution does not produce a precipitate. b) Why does the addition of 12M to the KCl solution produce a precipitate?
4. Why does Cds dissolve in HCI, when CuS and Bi2S3 will not?
