Interpretation Introduction

Interpretation:

In the titration of $\text{0}\text{.100M}$ trimethylammonium bromide with $4.0mL\text{ 0}\text{.100M NaOH}$ the $pH$ after $10.00mL$ $\text{0}\text{.100M}$ trimethylammonium bromide has to be calculated using activity coefficients.

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

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

Ionic strength of a solution corresponds to measure of concentration of ions in the solution and it is denoted by $\mu .$

Activity co-efficient is the ratio between chemical activity and actual concentration of the species.  It refers to the measurement of species in the solute which are actually taking part in a chemical reaction also called active species in a chemical reaction.  It is denoted by $\gamma .$
