Good Titrations- Ode to a Lab Partner by Kurt Wood and Jeff Lederman (sung to the tune of "Good Vibrations" by the Beach Boys) Ah! I love the color of pink you get, And the way the acid drips from your buret. All the painful things in life seem alien As I mix in several drops of phenolphthalein. I'm pickin' up good titrations She's givin' me neutralizations Dew drop drop, good titrations... I look at you and drift away: The ruby red turns slowly to rosé You gaze at me and light my fire As drop on drop falls to the Erlenmeyer... I'm pickin up good titrations She's givin' me neutralizations Dew drop drop, good titrations.. I look longingly to your eyes But you stare down at the lab bench in surprise. Gone our love before it grew much sweeter, Cause we passed the end point by a milliliter. I'm pickin' up back titrations She's prayin for neutralizations Dew drop drop, good titrations... Based on the information above, identify, to the best of your ability, the analyte and the titrant in the reaction, Justify your answer briefly

Explanation / Answer

The analyte is a base, while the titrant is an acid.

This is because it is written that drops of acid fall from the burette, which shows that acid is present in the titrant tube.

Also, phenolpthalein is pink in basic solution and turns colorless in acidic solution. This is the reason that initially the color is pink because the anaylte is basic, and as the solution becomes acidic because the end point is passed by adding excess 1 mL of the acid, the color disappears.

Hope this helps !
