Introduction

$T h e v o l u m e o f N a O H u s e d i n t h e t i t r a t i o n i s g i v e n a s : F i n a l v o l u m e o f N a O H (m L) - I n i t i a l v o l u m e o f N a O H (m L)$

Trial 1

$T r i a l 1 : I n i t i a l v o l u m e o f N a O H = 0.24 m L F i n a l v o l u m e o f N a O H = 44.94 m L$

$\begin{array}{rcl} V o l u m e o f N a O H u s e d & = & V_{f i n a l} - V_{i n i t i a l} \\ = & 44.94 m L - 0.24 m L \\ = & 44.70 m L \end{array}$

$44.70 m L o f N a O H i s u s e d i n T r i a l 1 .$
