A buffer containing 1.2169 M of acid, HA, and 0.1431 M of its conjugate base, A-, has a pH of 3.96. What is the pH after 0.0017 mol NaOH is added to 0.5000 L of this solution? I can't figure this out for the life of me, i'm sure its just some simple mistake i'm making but can ...

CHEMISTRY HELP!
(1) A beaker with 165 mL of an acetic acid buffer with a pH of 5.00 is sitting on a bench top. The total molarity of the acid and conjugate base in the buffer is 0.100M. A student adds 7.20mL of a 0.320M HCl solution to the beaker. How much will the pH change? The pka of ...

Hey, holidays is over. Time to get back to work. whats the answer to this one find the concentration of hcl in g hcl/kg Naoh + Hcl---> b +c 2.991 mol 25.00mL Density=0.952g/ml also Hcl=36.46g/mol I got approx 4.58 x 10^3 g/mol of the top of my head

Organic Chemistry
We've been working on extraction of known/unknown compound mixtures lately, and we have to give equations for the acid-base reactions that occurs between HCl, NaOh and (a) R-COOH (b) R-NH2, and (c) Neutral compounds (naphthalene and triphenylmethanol) For (a) carboxylic acids...
