Weak Acid + Strong Acid Base Titration - Example Problem: Consider Titration of 25 mL of .1 M CH3CO2H With .1 M NaOH. Calculate The pH After Adding The Following Volumes of NaOH: a. 0 mL b. 12.5 mL c. 25 mL d. 37.5 mL - I know that the correct the answer for letter d. is 12.28. I just don't know how to get to this answer.

Consider the titration of a 35.0 mL sample of 0.175 M HBr with 0.200 M KOH. Determine each of thefollowing.   e) the pH after adding 5.0 mL of base beyond the equivalence point

Build a titration curve for the following scenarios. Make sure to label your accesses and anyother appropriate pieces of data. Each curve should have a minimum of 4 data points, but youcan use the following to help structure your curvea) Initial pHb) pH at Veqc) pH=pka (if applicable)d) pH when excess titrant is addede) Additional pH point near Veq for Strong Acid/Strong Base titrations (in order to see thesteepness of the slope) OR additional pH point in buffer zone for titrations with a Weakcompound.

For which of the following aqueous solutions will a decrease of pH increase the solubility? A) CaCO₃ B) PbCl₂ C) CuBr D) AgCl

A1 liter solution contains 0.335 M acetic acid and 0.446 M sodium acetate. Addition of 0.368 moles of potassium hydroxide will: (Assume that the volume does not change upon the addition of potassium hydroxide.) Raise the pH slightly | Lower the pH slightly | Raise the pH by several units O Lower the pH by several units O Not change the pH O Exceed the buffer capacity
