Qualitative Analysis Qualitative is where the results give a colour that you have to match up to a colour chart‚ or have you have done to see if it is positive or negative with a description of what a positive reaction should look like. This test is less reliable as some colour or positive reaction look similar to each other or the same but by adding different chemicals. An example of qualitative would be a pH test as the result gives you a colour and then you have to match it up to the pH scale

Analysis of an Antacid In this lab report we will discuss the results of the ‘Determining the Most Effective Antacids’ lab. In this lab we tested different brands of antacids to find out which will be the most effective at neutralizing acids. We will test this by seeing how much drops of hydrochloric acid (HCl) are required to neutralize a certain amount of the antacid. Antacids are used to resist heartburn. We sometimes use them to treat this because antacids are a mild base that can neutralize
