KCET2015Chemistrys Block Elements
The pair of compound which cannot exist together in solution is
Options
- A( NaHCO ₃ ) and ( N a OH )
- B( NaHCO ₃ ) and ( H ₂ O )
- C( NaHCO ₃ ) and ( N a₂ CO ₃ )
- D( Na ₂ CO ₃ ) and ( NaOH )
Correct answer
A. ( NaHCO ₃ ) and ( N a OH )
Step-by-step solution
( NaHCO ₃ ) is unstable with ( NaOH ), because ( NaHCO ₃ ) is a basic salt, therefore, will react with ( NaOH ) and form ( Na ₂ CO ₃ ) and water ( NaHCO ₃+ NaOH Na ₂ CO ₃+ H ₂ O )
