WebApr 9, 2024 · We know that the total volume is 100 mL, so: V A− ≈ 100 −V HA in units of mL Therefore, we now have: 0.6310 = 0.240 M × (100 −V HA) 0.100 M ×V HA For ease of notation, let x = V HA. Then we have implied units: 0.6310 = 0.240(100 − x) 0.100x = 24.0 − 0.240x 0.100x 0.0631x = 24.0 −0.240x (0.0631 +0.240)x = 24.0 ⇒ x = V HA = ( 24.0 0.0631 … WebApr 8, 2013 · 1 Answer. Sorted by: 7.

WebQuestion: Calculate the final pH in each of the titration scenarios below: A. The titration of 25.00 mL of 0.160 M HCl with 15.00 mL of 0.242 M NaOH. Keep your answers to two decimal places. 4 B. The titration of 25.00 mL of 0.100 M CH3COOH (Ka of CH3COOH = 1.7 x 10-5) with 12.5 mL of 0.200 M NaOH. Keep your answers to two decimal places WebThe solution only has salt (NaCl) and water and therefore the pH is neutral i.e. pH = 7. Point 4: Addition of NaOH continues, pH starts becoming basic because HCl has been completely neutralized and now excess of OH ^\text {-} - ions are present in the solution (from … WebApr 23, 2024 · pH = 1.10 Explanation: First thing first, calculate the total volume of the resulting solution V total = 100.0 mL + 50.0 mL + 100.0 mL V total = 250.0 mL Now, you are dealing with two strong acids that ionize completely in aqueous solution. Both nitric acid and hydrochloric acid produce hydronium cations in 1:1 mole ratios, so you know that candyland decor ideas
