Question

To demonstrate a double displacement reaction , the solutions of sodium sulphate and barium chloride are mixed .(a) What is the colour of the precipitate formed? Name the compound precipitation .(b) Write the balanced chemical equation for this reaction .

Answer 1

a- white ppt
b- sodiumchloride and barium sulphate
c- given in photo

Answer 2

Answer: For a) The color of the precipitate formed which is Barium sulfate is white.

For b) $Na_2SO_4(aq.)+BaCl_2(aq.)\rightarrow BaSO_4(s)+2NaCl$

Explanation:

Double displacement reactions are the reactions in which exchange of ions takes place. The reaction between sodium sulfate and barium chloride is given by the equation:

$Na_2SO_4(aq.)+BaCl_2(aq.)\rightarrow BaSO_4(s)+2NaCl$

Here, barium sulfate is the precipitate formed which is white in color.

Hence,

For a) The color of the precipitate formed which is Barium sulfate is white.

For b) $Na_2SO_4(aq.)+BaCl_2(aq.)\rightarrow BaSO_4(s)+2NaCl$
