What is the product when aluminum reacts with aqueous alkali?
Options
- ASodium hydroxide
- BAluminum chloride
- CSodium tetrahydroxoaluminate(III)
- DHydrogen peroxide
Correct answer
C. Sodium tetrahydroxoaluminate(III)
Step-by-step solution
The reaction equation: 2Al (s) + 2NaOH(aq) + 6H 2 O(l) → 2 Na+[Al(OH) 4 ]–(aq) + 3H 2 (g), indicates the formation of sodium tetrahydroxoaluminate(III).
