Question

When zinc reacts with sodium hydroxide what is the product? Write the equation.

Answer 1

Answer:

It will not react as Zn is lower than Na in reactivity series

Answer 2

Answer:

$Z n+2 N a O H \stackrel{t^{\circ} C}{\rightarrow} N a_{2} Z n O_{2}+H_{2}$

Explanation:

"Zinc react with sodium hydroxide (NaOH)" to produce "sodium zincate and hydrogen". The reaction take place at temperature of about 550° C. The product formed is highest at this temperature .

The product decreases at temperature higher or lower than this temperature. High temperature shift an equilibrium of reaction. The hydrogen formed rises in the medium due to its low weight.

One mole of zinc reacts with two miles of sodium hydroxide.
