Explain Activity 1.10 Class 10 NCERT Science |
Observation-
in this reaction. it is observed that an
insoluble white solid substance is formed.
Explanation
When sodium sulphate and barium chloride react, a double displacement
reaction takes place.
After the exchange of ions between compounds, a white solid substance of
barium sulphate is formed and sodium chloride remains in the solution.
Conclusion-
The insoluble white substance formed is known as a precipitate.
Na2SO4(aq)
+ BaCI2(aq) → BaSO4(s)
+ 2NaCI(aq)
This is also known as Precipitation Reaction.
