Which of the following reactions does no liberate gaseous product ?
Options
- AAlCl ₃+ NaOH
- BNaOH + P (white ) + H ₂ O
- CAl + NaOH
- DZn + NaOH
Correct answer
A. AlCl ₃+ NaOH
Step-by-step solution
When AlCl ₃ reacts with NaOH , it forms sodium meta aluminate ( NaAlO ₂ ) . This reaction does not give gaseous product. AlCl ₃+4 NaOH NaAlO ₂ (Sod. meta aluminate (soluble)) +2 H ₂ O +3 NaCl
