What else can I help you with?
To test the purity of calcium chloride you dissolve a 3.77g sample in water and add silver perchlorate to precipitate out silver chloride.?
By adding silver perchlorate, any chloride ions present in the solution will react with the silver ions to form silver chloride precipitate. The mass of silver chloride can be measured to determine the amount of chloride present, which can then be used to calculate the purity of the calcium chloride sample.
What happens when sodium carbonate and calcium chloride are combined?
When sodium carbonate and calcium chloride are combined, a reaction occurs that forms calcium carbonate (a white precipitate), sodium chloride, and water. This reaction is a double displacement reaction where the ions in the two compounds switch partners to form new compounds.
Does barium chloride plus sodium chloride form a precipitate?
No, barium chloride and sodium chloride will not form a precipitate when mixed together as both salts are soluble in water.
When calcium chloride and water and baking soda were combined what things were formed?
When calcium chloride and water are combined, calcium chloride dissolves in the water to create a solution. When baking soda is added to the solution, it reacts with the calcium chloride to form calcium carbonate, water, and carbon dioxide gas.
Will water dissolve calcium chloride?
Yes, water will dissolve calcium chloride. Calcium chloride is highly soluble in water, so it will readily dissolve and form a clear solution.
Does CaCl2 form a precipitate?
No, calcium chloride will dissolve in water.
Which calcium salts precipitate?
Calcium carbonate and calcium phosphate are common calcium salts that can precipitate in certain conditions. Calcium carbonate can precipitate in alkaline solutions, while calcium phosphate can precipitate in acidic solutions.
Barium sulfate plus calcium chloride?
When barium sulfate is mixed with calcium chloride, a double displacement reaction occurs where barium chloride and calcium sulfate are formed. Barium chloride is soluble in water, while calcium sulfate is not, so a solid precipitate of calcium sulfate will form.

Does barium chloride plus sodium chloride form a precipitate?
No, barium chloride and sodium chloride will not form a precipitate when mixed together as both salts are soluble in water.
If calcium chloride (CaCl2) is added to silver nitrate (AgNO3) what precipitate will form?
The chemical reaction is:CaCl2 + 2 AgNO3 = 2 AgCl(s) + Ca(NO3)2The precipitate is silver chloride.
Does calcium chloride form ions in water?
Calcium chloride, or CaCl2, is an ionic salt comprised of calcium (C) and chlorine (Cl). CaCl2 disassociates when added to water into calcium cations and chloride anions.
Is precipitate form when calcium chloride and sodium hydroxide react?
CaCl2 (solubility 745g/l) NaOH (solubility 1090g/l) CaCl2 + 2NaOH > Ca(OH)2 + 2NaCl (Double displacement reaction) Ca(OH)2 (Solubility 1.7g/l) NaCl/Table salt (Solubility 359g/l) I'm assuming that you'll be left with Calcium Hydroxide as a precipitate because it's not soluble whereas all other chemicals involved are soluble you should get a White precipitate of Calcium precipitate (Hydroxides aren't very soluble generally unless paired with an alkali metal)

What happens when you combine a sodium carbonate solution to calcium chloride?
When a sodium carbonate solution is combined with calcium chloride, a double displacement reaction occurs. The sodium carbonate reacts with the calcium chloride to form calcium carbonate (a white precipitate) and sodium chloride. This reaction can be written as: Na2CO3 + CaCl2 -> CaCO3 + 2NaCl.
