I'm not sure If i have the right answer can someone help?
Homework Answers
a) CH3COOH + NaOH ---------> CH3COONa + H2O
at stoichiometric point all CH3COOH reacted with NaOH
so solution contain CH3COO- and Na+ ions only
b) CH3COOH + NaOH ---------> CH3COONa + H2O
halfway point means 50% acid convert to CH3COONa
so aolution contain CH3COOH , CH3COO- and Na+ ions

Which of the statements below is/are true of your solution at equivalence? Select all true statements below. The concentration of acetate ions (CH2C00) at equivalence is the same as the original concentration of acetic acid (CH2COOH) at the start of the titration (i.e. 1.0 M). The number of moles of acetate ions (CH3COO") at equivalence is the same as the number of moles of of acetic acid (CH2COOH) at the start of the titration (i.e. 0.10 mol). At the equivalence...

Acid-Base Titration of a Weak Acid with a Strong Base: Determination of K. Introduction: You will be titrating a solution of a weak acid with 0.100 M NaOH, while monitoring the reaction using a pH meter. Weak acids have characteristic acid-ionization constants, K. The purpose of this lab is to use the titration to determine the value of this constant for the weak acid called “benzoic...

I'm not sure about how I'm supposed to find NaOH
concentration from a strong acid and strong base titration. I'm
thinking that 2.5×10^-8 mol per L that I calculated would make the
moles of NaOH 2.5x10^-8 mol since it's a one to one
ratio.

To add more information this was given to me for a lab that used
a weak acid and we added a strong base through titration. We just
observed how the ph changes. Later we then used a buffer with a
weak acid to see how buffers affect ph change. These questions are
basically surrounded around those topics to help us prepare.
However, I'm kinda confused about answering them because weak...
