When they react K2SO4 and BaBr2 they'll give 2KBr and BaSO4:

SO42-aq + Ba2+aq ---> (BaSO4)s ('s' = solid = precipitating bariumsulfate)

2K+ and Ba2+ are spectator ions (all 'aq' = hydrated in solution)

What is a balanced chemical equation for barium chloride plus Potassium sulfate?

The balanced chemical equation for barium chloride (BaCl2) reacting with potassium sulfate (K2SO4) is: BaCl2 + K2SO4 -> BaSO4 + 2KCl. This reaction forms barium sulfate (BaSO4) and potassium chloride (KCl).


What is the chemical equation for the reaction between barium chloride and potassium sulfate?

The BaSO4 (barium sulfate) will precipitate out of solution because it is insoluble, whereas the KCl2 is soluble and will remain dissolved. The balanced equation is: K2SO4 + BaCl2 -----> 2KCl + BaSO4


What is the unbalanced chemical equation when potassium bromide reacts with barium iodide to produce potassium iodide and barium bromide?

What is the formula unit for potassium sulfate and barium chloride are mixed to form potassium chloride and barium sulfate?

The balanced chemical equation for this reaction is K2SO4 + BaCl2 → 2KCl + BaSO4. The formula unit shows the ratio of ions combining to form the products: 2 potassium ions combine with 1 sulfate ion to form potassium sulfate, while 1 barium ion combines with 2 chloride ions to form barium chloride.


What is the reaction between barium chloride and potassium sulfate?

The reaction between barium chloride and potassium sulfate results in the formation of insoluble barium sulfate and soluble potassium chloride. This is a double displacement reaction where the cations and anions switch partners. The balanced chemical equation for this reaction is BaCl2 + K2SO4 -> BaSO4 + 2KCl.


What is the chemical equation for barium nitrate and potassium sulphate?

The chemical equation for the reaction between barium nitrate (Ba(NO3)2) and potassium sulfate (K2SO4) is Ba(NO3)2 + K2SO4 -> BaSO4 + 2KNO3. It forms barium sulfate (BaSO4) and potassium nitrate (KNO3) as the products.


What is the balanced equation for barium sulfate is oxidized to barium sulfate by atmospheric oxygen?

Barium sulphate to barium sulphate is NO CHANGE!


Will a precipitate form if solutions of potassium sulfate and barium nitrate are combined?

Yes, a precipitate of barium sulfate will form because barium ions (Ba²⁺) from barium nitrate react with sulfate ions (SO₄²⁻) from potassium sulfate to form an insoluble compound, barium sulfate (BaSO₄). This insoluble compound will precipitate out of solution.


What happens when barium chloride reacts with potassium sulfate?

When barium chloride reacts with potassium sulfate, a double displacement reaction occurs. Barium sulfate and potassium chloride are formed as products. BaCl2(aq) + K2SO4(aq) → BaSO4(s) + 2KCl(aq). Barium sulfate is insoluble in water and precipitates out as a white solid.


What is the reaction of potassium chromate with barium sulphate?

When potassium chromate reacts with barium sulfate, a precipitation reaction occurs. Barium chromate is formed as a yellow precipitate, while potassium sulfate remains in solution. This reaction can be used to detect the presence of sulfate ions in a solution.
