Chapter 18.4, Problem 54SSC

Interpretation Introduction

Interpretation:

The titration of nitric acid with cesium hydroxide and the way to calculate molarity is to be discussed including writing the formula and net ionic equation.

Concept introduction:

In acid- base titration, an indicator is used to detect the neutralization point.

Answer to Problem 54SSC

Formula equation:

$HN{O}_3+CsOH\to CsN{O}_3+H_{2}O$

Net ionic equation:

$H^{+}+O{H}^{-}\to H_{2}O$

Explanation of Solution

To calculate the molarity of cesium hydroxide, a fixed volume of it is added in titration flask and few drops of indicator. The burette is filled with nitric acid of known concentration. Drop by drop nitric acid is added. The volume of acid used for neutralization is noted. Then applying the molarity equation $M_1{V}_1=M_2{V}_2$, molarity of cesium hydroxide is calculated.

Conclusion

Formula equation:

$HN{O}_3+CsOH\to CsN{O}_3+H_{2}O$

Net ionic equation:

$H^{+}+O{H}^{-}\to H_{2}O$
