NEETChemistryp Block Elements (Group 15, 16, 17 & 18)
Give reasons: (ii) A mixture of dilute NaOH and aluminium pieces is used to open drain.
Options
- AThe reaction between aluminium and dilute sodium hydroxide produces hydrogen gas, which exerts pressure and he
- BAluminium reacts with sodium hydroxide to form sodium aluminate and hydrogen gas, which helps break down organ
- CDilute sodium hydroxide reacts with aluminium to form sodium aluminate, a compound that effectively dissolves
- DThe heat generated by the reaction between aluminium and dilute sodium hydroxide helps melt and dislodge clogs
Correct answer
A. The reaction between aluminium and dilute sodium hydroxide produces hydrogen gas, which exerts pressure and he
Step-by-step solution
Correct Option is : (A) The reaction between aluminium and dilute sodium hydroxide produces hydrogen gas, which exerts pressure and helps in dislodging clogs in the drain.
