AI Thread Summary
The discussion focuses on calculating the pH after adding varying volumes of 0.32M HCl to 25 mL of 0.16M NaOH. Participants are seeking assistance with specific volumes, particularly from 1 mL to 15 mL, after successfully calculating the pH for 0 mL. The neutralization reaction between NaOH and HCl requires determining the excess moles of either acid or base to find the resulting pH. A key relationship mentioned is that pH and pOH sum to 14, which is essential for these calculations. The thread emphasizes the importance of correctly converting volumes to moles for accurate pH determination.

Chemistry pH problem help please NaOH and HCl

Calculate the pH after the following total volumes of .32M HCl have been added to 25 mL of 0.16M NaOH
a. 0 mL c. 12.4 mL e. 12.6 mL
b. 1 mL d. 12.5 mL f. 15.0 mL



A. i have answered correctly but i can't seem to get the right answer for any of the others i tried putting them in mmol but it never seems to work if someone could just tell me how to do b through f i would be very pleased thank you.

The exercise is a neutralization reaction. Determine which moles of NaOH or HCl is in excess. That would be the one which affects the pH. A relationship which is helpful is 14 = pH + pOH

Thread 'Confusion regarding a chemical kinetics problem'

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...
