Basic oxides
Continue equations 1-6 by following the respective general equations. Equations
1-3 can be continued using reaction 1, while equations 4-6 can be continued by
using reaction 2.
Reaction 1
Basic oxide+ water→ metal hydroxide
1. K2O+H2O
→
2. BaO+H2O →
3. Rb2O+H2O →
Reaction 2
Basic oxide+ acid→ salt
+ water
4. CaO+H2SO4→
5. K2O+HNO3 →
6. Na2O+H2SO4→
Note : the salt is formed when the metal replaces the hydrogen from the acid.
