Unfortunately, humanity has discovered a new virus that was discovered on the planet Venus. It has been shown that this virus will only become active at a pH less than 2. You are presented with a sample of the virus in an acidic solution. The solution's volume is 10.5 mL. You perform a titration on the sample and find it takes 24.6 mL of a 0.10 M solution of sodium hydroxide to neutralize it.

There are two questions here:

1) What would be the concentration of the original acid solution? You may assume the acid is strong and can be abbreviated as H-X.

2) What would be the pH of the original solution? Remember strong acids completely dissociate in water, thus the [acid] = [H3O+].

Write the empirical chemical formula of calcium with a mass percent of 38.8, phosphorus with a mass percent of 20.0, and oxygen with a mass percent of 41.3.

Straightforward questions answered in the powerpoint slidesreaction: heating the starting materials under refluxwhat does it mean to heat under reflux? why do we choose water as the reflux solvent? what are boiling chips used for? why do we put a condenser on top of the reaction? why do we add heat and let the reaction stir for 30 minutes? why do we add sulfuric acid to the reaction after it cools as opposed to when it’s still hot? separation: filtration of precipitatewhy don’t we do an aqueous and organic extraction in the separatory funnel? why do you rinse the salicylic acid on the filter with ice cold water? purification: recrystallization of salicylic acid (no hot filtration needed)what is the difference in the amount of room temperature water vs. boiling water needed to dissolve the salicylic acid (assume a 1.2 gram yield of salicylic acid)? remember, in the lab if you need x ml of boiling water to dissolve a solid, then you should add a little more (definitely no more than 1.5 times the theoretical amount) to ensure it doesn’t recrystallize prematurely.analysis: melting point of salicylic acidwhat can you conclude if the melting point of the salicylic acid you just synthesized is 152-155oc and the 1: 1 mix of your product and “synthetic” salicylic acid is 151-154oc?
