I'm making an experiment and I need to calculate how much vinegar (acetic acid) and baking soda (sodium bicarbonate) is needed to make a 0.1 M buffer at a pH of 7. How do I calculate what quantities of acetic acid and sodium bicarbonate needed to prepare this using the Henderson-Hasselbalch equation? I know that the concentration of acetic acid in vinegar is 0.845 M and the pKa is 4.76. I also know that the molar weight of sodium bicarbonate is 84 g/mol. The solubility of sodium bicarbonate in water is about 8.7g in 100 g of water. Please help!

Expert Solution
Introduction

Buffer solutions are used to resist the addition of a strong base or strong acid. The pH of buffer solutions changes only slightly when any strong acid or base is added to it.
