Question

Имеются растворы сульфата калия и хлорида бария.Как их различить?Ответ поясните и приведите уравнения реакций.

Answer 1

K2SO4+BaCL2=BaSO4+2KCl
BaCl2+2AgNO3=2AgCl+Ba(NO3)2

Answer 2

Differentiating Between Potassium Sulfate and Barium Chloride Solutions

To differentiate between potassium sulfate (K2SO4) and barium chloride (BaCl2) solutions, we can use the following chemical reactions:

1. Reaction with Sodium Carbonate (Na2CO3): - When a solution of potassium sulfate reacts with sodium carbonate, it forms a precipitate of potassium carbonate, while barium chloride forms a precipitate of barium carbonate. - The chemical equations for these reactions are: - For potassium sulfate: ``` K2SO4 + Na2CO3 → K2CO3 + Na2SO4 ``` - For barium chloride: ``` BaCl2 + Na2CO3 → BaCO3 + 2NaCl ```

2. Reaction with Sulfuric Acid (H2SO4): - When a solution of barium chloride reacts with sulfuric acid, it forms a white precipitate of barium sulfate, while potassium sulfate does not react with sulfuric acid in the same way. - The chemical equation for this reaction is: ``` BaCl2 + H2SO4 → BaSO4 + 2HCl ```

By performing these reactions, we can differentiate between the two solutions based on the formation of specific precipitates.
