5b) Part 1: Fill in the values below from your calculations for 10.0 mL 1.00 M HCI added to 50.0 mL of Buffer B. Number of moles converted = mol conj. acid/base Total volume of mixture = L solution Moles and Volume: Include numbers only, with correct significant figures and leading zeros 5b) Part 2: Fill in the values in the equation below for 10.0 mL 1.00 M HCI added to 50.0 mL of Buffer B. Change in pH = pH final - pH initial = Answer Change in pH = - 7,000 = pH values: Include numbers only, with correct significant figures, no space between sign and number, include leading zeros
