Even if you've never set foot in a chemistry lab, chances are you know a thing or two about acids and bases (a conjugate acid-base pair) khan academy is a. Acid - base titration lab reports purpose: the purpose of the titration is to determine the amount of acid it contains by measuring the number of ml of the standard naoh need to neutralize it. This activity is building on the prior knowledge from the properties of water lecture notes that discusses acids, bases, and the ph scale that were shared in a prior lesson student inquiry lab development : in the past (pre-ngss), students were usually provided a teacher-developed lab that outlined a step-by-step procedure that all students. We converted both benzoic acid and 2-naphthol to their conjugate bases, which are soluble in water, in two separate steps, with two separate bases the weak base (bicarbonate) converted the stronger acid (benzoic acid, a carboxylic acid) into its conjugate base (benzoate) while leaving the other species in the immiscible phase.
