Quantitative Analysis

Analytical chemistry studies and uses instruments and methods to separate, identify, and quantify matter. When trying to determine the concentrations of unknown samples of acids or bases, a volumetric analysis technique called titration is used. It is highly accurate, easy to perform (once you learn it), and does not require any expensive equipment. 

At this stage, you should have found out the main acid/base involved in your investigation and the equilibrium concentrations of ions it dissociates into. Watch the video below and add comments with a timestamp if you have any questions then try the Quizizz practice assignment.   

Find literature to give you an rough idea of how many moles of acid or base you're expecting to find in a sample for your investigation, then calculate the amount of known acid/base needed to neutralize it. For example, if you are investigating the acidity of Sprite, find the main acid it contains then calculate the H+ ions in a certain volume being tested, then based on the mole ratio between the reaction of the acid and NaOH, calculate the volume of NaOH needed to neutralize a certain volume of Sprite. By doing this, you can have a better idea of the approximate volumes needed in your titration experiment.
