Lindsey L asked:
Information:
Information:
25 mL of 0.20 M HC2H3O2 = .005 moles of HC2H3O2
22.99 moles of NaC2H3O2 = 82.04 grams of NaC2H3O2
Use:
pH = pKa + log [NaC2H3O2]/[HC2H3O2]
finding pKa is confusing me?

The only information that I’m given is the molar concentration (in g/mol) of the acetic acid and the acetate
They are both 0.1g/mol

hey i need help rearanging this equation to make pKa the subject:
pH= pKa +log[HA]/[A]
cuz i need to calculate pKa
thank you to the person that answered it … i wasnt sure if it could be done that way .. thanks again …
