3 I need to find the Ka of a weak acid in titration with a strong base 2 pH 10 to pH9 NaOH dilution 3 How to create a buffer using CH3COOH and CH3COONa that has a pH of exactly 3.75? 3 Accurate method to calculate the pH of a salt from a weak acid and weak base...
Draw the structure of its conjugate base and explain why acetamide is less acidic than CH3COOH. What does the pK_a really tell you about the strength of the acid (H) bond in the molecule? If H2O has ...
Calculate the pH of a solution prepared by dissolving 2.20 g of sodium acetate, CH3COONa, in 74.5 mL of 0.20 M acetic acid. (Ka of CH3COOH is 1.75 x 10^-5) Calculate the pH of a buffer with different moles of a weak acid and conjugate base: 0.010 L of 0.10 M acetic acid, and...
CH3COOH + H2O arrow H3O+ + CH3COO- Which of the following acids is the WEAKEST? The acid is followed by its Ka value. Which of the following acids is the WEAKEST? The acid is followed by its Ka value. a.HCN, 4.9 x 10^-10 b.HNO_2, 4. What are the pka values of the acids...
