5. Please calculate the pH of a solution containing 0.40 M CH,COOH and 0.70 M CH3COONa (K, acetic acid = 1.8 X 10"): CH3COOH + H+ + CH3COO CH3COONa → CH3COO + Nat 6. The molar solubility of tin(ll) iodide is 1.28 x 10-2 mol/L. What is Ksp for this compound?
What is the pH of a buffer that consists of 0.45 M CH3COOH and 0.35 M CH3COONa? Ka = 1.8 x 10-5 So the answer is 4.64. However, I was under the impression that it is Ka * (base/acid). So wouldn't that be 1.8 x 10^-5 * (.35/.45)? Isn't the CH3COONa the base? Someone please explain. Thank you.
