Question
nts ago, in CSI Miami (making forensic science look fun to the masses since 2002) the action developed The bad guy (there is always one) wanted to get rid of the other bad guy who could not keep his mouth shut. To do that, a set up ensued in which the 'soon to be deceased" fell into a pool and literally dissolved. The dialogue developed as follows: Horatio: It looks like the pool has been filled with alkali Delko: alkali? Horatio: yes, we have to take care of this before forensics arrive, or we will end up without evidence..bring me some vinegar. Delko: vinegar? Horatio: yes, it will neutralize the alkali and we will be able to retrieve him. Delko: This is going to take a lot of vinegar; I'll better go to the store. (Or something along those lines... was laughing so hard I cannot recall the dialogue verbatim) What type of reaction is Horatio proposing? Later, we find that the pool was indeed filled with a sodium hydroxide solution. For the sake of argument believe me when I tell you that injuries so grave could only be inflicted by a solution with a three-molar or higher concentration Dead guy, being a mob boss, had a big pool. deep. Let say an above average residential pool of 25 x 26 feet, 5 feet a) If there was an open Costco within driving distance and the store held a big supply of one-gallon containers of Sarson's pickling vinegar 20% acetic acid in volume how many containers did Delko need to neutralize the pool? Answer: b) Later on, we find that bad guy was really sneaky and introduced the sodium hydroxide into the pool's filtration system. Looking at the Hayward Pro Grid D.E. Filter specs, the biggest filter they carry (one that would work in bad guy's pool) is a cylinder that measures 61 cm in diameter and 133 cm tall. Could this filter hold enough solid sodium hydroxide to turn the pool's water into a deadly three molar solution? (Assume that crystalline sodium hydroxide has a density of 2.13 g/cm2) Answer, circle one c) How much space is needed to fit all the necessary sodium hydroxide? Answer YES NO d) Based on your calculations, what is the highest molar concentration of sodium hydroxide that could be achieved, assuming the filter was completely full of sodium hydroxide? Answer:Explanation / Answer
Vinegar is acetic acid and reaction with alkali will lead to formation of salt and water which is neutralization reaction.
