Question

Complete the following reactions
(i) Al2O3(s) + ............. ⎯⎯→ 2NaAlO2 + H2O(l)
(Sodium aluminate)
(ii) CaO(s) + ............. ⎯⎯→ Ca(OH)2
(iii) Sn(s) + .............+ H2O(l) ⎯⎯→ Na2SnO3
(Sodium stannate)

Answer 1

Answer:

(i) Al2O3(s) + $2 NaOH (aq)$ ⎯⎯→ 2NaAlO2 + H2O(l)

(ii) CaO(s) + $H_{2}O$ ⎯⎯→ Ca(OH)2

(iii) Sn(s) + $2 NaOH (aq)$ + H2O(l) ⎯⎯→ Na2SnO3
