Explanation:
When zinc is added in sodium solution sodium zincate (Na2ZnO2) is formed along with hydrogen gas.
2NaOH+Zn→Na2ZnO2+H2
When burning splint is held near the evolved it continues burning with pop sound indicating evolution of Hydrogen gas.
Same metal i.e Zn reacts with strong acid H2SO4 to give ZnSO4
Zn+H2SO4→ZnSO4+H2↑
