Dazzling experiment at Innovation Hub SSC Patna

Описание: Dazzling experiment at Innovation Hub, SSC Patna.
Mag­ne­sium is an ac­tive met­al, but its sur­face is cov­ered with a durable ox­ide film. On heat­ing this film dis­in­te­grates and the mag­ne­sium burns with a blind­ing white flame. The met­al burns with the for­ma­tion of mag­ne­sium ox­ide and ni­tride. In the wa­ter va­por the mag­ne­sium burns even more strong­ly, as mag­ne­sium forces the hy­dro­gen out of wa­ter, the re­leased hy­dro­gen ig­nites, and the flame in­ten­si­fies. Mag­ne­sium hy­drox­ide forms, a weak base which turns the wa­ter con­tain­ing phe­nolph­thalein a pink col­or.
2Mg + O₂ → 2MgO

3Mg + N₂ → Mg₃N₂

Mg + H₂O → MgO + Н₂

Mg + 2H₂O → Mg(OH)₂ + Н₂

MgO + H₂O → Mg(OH)₂
