Chapter 7, Problem 52E

Interpretation Introduction

Interpretation:

The metals that react with water at room temperature are to be stated.

Concept Introduction:

There are few metals in the periodic table that are so reactive that they react directly with water at room temperature. These metals are called active metals. The active metals are $\text{Li}$, $\text{Na}$, $\text{K}$, $\text{Rb}$, $\text{Cs}$, $\text{Ca}$, $\text{Sr}$ and $\text{Ba}$. Sodium $\left(\text{Na}\right)$ is an active metal and react with water at room temperature as shown in reaction below.

$2\text{Na}\left(s\right)+2{\text{H}}_{\text{2}}\text{O}\left(l\right)\to 2\text{NaOH}\left(aq\right)+{\text{H}}_{\text{2}}\left(g\right)$
