Chapter 11, Problem 11.GE

Interpretation Introduction

Interpretation:

For the titration of weak acid with $0.09381M\text{ NaOH}$ the $pH$ when $19.47mL\text{ of NaOH}$ added has to be calculated.

Concept introduction:

Acid-base titration is titration between acid and base. It is also known as neutralization reaction.

There are primarily four types of acid-base titrations –

• Strong base vs strong acid
• Strong base vs weak acid
• Weak base vs strong acid
• Weak base vs weak acid

Equivalence point ensures the titration reaction becomes completed and at this point the number of moles of titrant and the number of moles of analyte remain equal.  The end point refers to the color change and indicates equivalence point has been reached.

The term $pH$ refers to concentration of $H^{+}$ion in a solution.
