MCQ
$BaCl _2+ Na _2 SO _4 \rightarrow BaSO _4+2 NaCl$. It is type of:
- ABoth Precipitation reaction and Double displacement reaction
- BDouble displacement reaction
- CDecomposition reaction
- DPrecipitation reaction
✓
Answer
Both Precipitation reaction and Double displacement reaction
Explanation:
• Double decomposition takes place, due to the exchange of ions between the 2 substances. A white precipitate of bariur sulphate is formed.
• $BaCl _2+ Na _2 SO _4 \rightarrow BaSO _4+2 NaCl$
• $BaSO _4$ is insoluble in water. NaCl dissolves in water.
• $BaSO _4$ is Barium Sulphate
• NaCl is common salt of Sodium Chloride
