Question

B. Preparation of NaOH solution

1. Molarity of concentrated NaOH used: 6 M

2. Volume of concentrated NaOH used: 5 mL

C. Standardization of the HCl solution

	Trial one	Trial two	Trial three
Initial HCl buret reading	50 mL (or 0.0)	50 mL	50 mL
Final HCl buret reading	40	40	40
Initial NaOH buret reading	50	50	50
Final NaOH buret reading	38.1	38.1	37.1

B. The molarity of NaOH used after dilation was 0.12 (6M x 5mL = M2 x 250 mL)
