    Acid Mass Method
AI Thread Summary
To determine the molar mass of the soluble acid X, a titration method using 0.1M sodium hydroxide (NaOH) is proposed. The discussion emphasizes the need to clarify whether to titrate acid X alone or in combination with potassium phthalate. Participants express confusion about the amount of acid to use and the calculations needed for the titration, including the grams of acid weighed and the moles of NaOH required. The neutralization reaction is suggested as HX + NaOH → NaX + H2O, prompting questions about the stoichiometry involved. Understanding these parameters is crucial for accurately calculating the molar mass of acid X.

HELP! How to find a method to determine the molar mass of a soluble acid X??

Homework Statement


I am provided with the following apparatus:
Monobasic Acid (KHC6H4O6) - Potassium Phthalate (Mr of about 202.4)
Aqueous Sodium Hydroxide (0.1M)
Indicator
Acid X monobasic (whose molar mass I have to find!)
Normal laboratory equipment

The question is to design a method to find the molar mass of the soluble acid x



Homework Equations


ACID + OH -- H20 + ACIDrest (I got this from my friend but I have no clue what this has to do with the stuff I have said above)


The Attempt at a Solution



What I came up with after a lot of thinking was a simple titration
I could titrate with NaOH. But then I am not sure whether to use some amount of acid x or the mixture of acid x and potassium phthalate or just potassium phthalate. I am really confused here!


Please Please HELP!

How many grams of acid material were weighed and dissolved for preparation for the titration?

How many moles of sodium hydroxide titrant at 0.1 M were used for the titration?

Could the neutralization reaction be represented as:
HX + NaOH ---------> NaX + HOH

? Then how many moles of sodium hydroxide are required for one mole of HX ?

If you want to find molar mass, then are you looking for how many grams per mole is the acid "HX"?

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
