When NaOH reacts with aluminium metal,the following reaction happens:
NaOH+Al+H2O→NaAlO2+Y
If Y is a gas, identify it.
H2
H2O
CH4
NO2
When any base reacts with metal, they always liberate hydrogen gas. 2Al+2NaOH+2H2O→2NaAlO2+3H2
So, Y is H2 gas.
When NaOH reacts with Aluminium metal, following reaction occurs:
NaOH+Al→Na[Al(OH)4]+Y
When NaOH reacts with metal a X, the following reaction takes place:
NaOH+X→Na2ZnO2+Y
Identify X and Y.
