Ph of 3.0 m ch3cooh
WebThe pH is equal to 9.25 plus .12 which is equal to 9.37. So let's compare that to the pH we got in the previous problem. For the buffer solution just starting out it was 9.33. So we … WebBecause pH = -log [H3O+]. The initial concentration of CH3COOH is not equal to [H3O+]. You need to do ICE in order to figure out how much H3O+ has been formed by the reaction of CH3COOH with water. ( 7 votes) kristofferlf 5 years ago

WebYou want to produce a CH3COOH /CH3COONa buffer with pH = 5.00 . What is the ratio of conjugate base to acid? You start by using the Henderson - Hasselbalch equation: pH = pKa + log ( [CH3COONa]/ [CH3COOH] pKa = - log (1.8*10^-5) = 4.74 5.00 = 4.74 + log ( [CH3COONa]/ [CH3COOH] log ( [CH3COONa]/ [CH3COOH] = 5.00–4.74 WebApr 30, 2024 · Long Answer. a) pH = 5.13; b) pH = 11.0 Explanation: For a): Ammonium chloride, N H 4Cl dissolves in solution to form ammonium ions N H + 4 which act as a weak acid by protonating water to form ammonia, N H 3(aq) and hydronium ions H 3O+(aq): N H + 4 (aq) +H 2O(l) → N H 3(aq) + H 3O+(aq)
WebApr 8, 2013 · 1 Answer Sorted by: 7 For (a), the Henderson-Hasselbalch equation, p H = p K a + log ( [ A X −] / [ H A]), comes in handy. Because your molarities and volumes of the acid … WebNow, you can see that sodium hydroxide and acetic acid react in a 1:1 mole ratio. This means that we need the same number of moles of NaOH as we have CH3COOH for a complete reaction. Using concentration and volume we can determine the #mol of NaOH used: n (NaOH) = CV = (0.0500 mol/L) (0.0150 L) = 7.50×10^-4 mol NaOH.
WebJun 23, 2016 · Explanation: Acetic acid, CH3COOH, is a weak acid, meaning that it partially ionizes in aqueous solution to form hydronium cations, H3O+, and acetate anions, …
