From this list, select metals that can react with sodium hydroxide: magnesium, zinc, aluminum, iron, tin, copper. write down the equations of possible reactions.

We are given a substance base sodium hydroxide, the chemical formula is NaOH. Let’s consider its interaction with different substances:

1) With magnesium, the reaction with sodium hydroxide does not work. Magnesium will not displace sodium from the base.

NaOH + Mg = does not go

2) Sodium hydroxide reacts with water and zinc, more precisely with an aqueous solution of zinc. A complex salt of sodium hydrozincate is formed and hydrogen is released.

2 NaOH + 2 H2O + Zn = Na2 [Zn (OH) 4] + H2 ↑

3) Sodium hydroxide and aluminum react to form sodium aluminate and hydrogen.

NaOH + Al = NaAlO2 + H2

4) Sodium hydroxide and iron form sodium hydride and tetravalent iron oxide after a chemical reaction.

4 NaOH + 3 Fe = 2 NaH + Fe3O4

5) Lead and sodium hydroxide react and form a complex salt of bivalent sodium trihydroxostanate.

Sn + NaOH + 2H2O = Na [Sn (OH) 3] + H2 ↑

6) The reaction of sodium hydroxide and copper does not proceed, since copper will not displace sodium from the base.

NaOH + Cu = not going.
