Question: Calculate the pH of an aqueous solution of HNO3 at the concentration of 0.5M. Its pH should be about 0.3 (and pH value has no unit). The questions you need to consider before performing this calculation are: i. How would I obtain the concentration of H∗,[H+], for use in the formula, pH=−log[H∗] ? See ii. ii.
Explanation: We use the pH equation, which states that. pH = −log[H +] or pH = − log[H 3O+] It is the same equation anyways, as water can dissociate two ways. Since the hydrochloric acid has a concentration of 0.34 M, that must mean that the concentration of hydronium (H 3O+) ions is also 0.34 M, i.e. there exists 0.34 moles of hydronium
The #"pH"# of this solution should be close to that in Part a), because the solution in Part a) is a buffer. c) After adding 0.10 mL NaOH The strong base will dissociate completely.
You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: Consider the titration of 50.0 mL of 0.20 M NH3 (Kb=1.8×10−5) with 0.20 M HNO3. Calculate the pH after addition of 50.0 mL of the titrant at 25 ∘C. Express the pH numerically.
Calculate the pH of a buffer solution that is 1.25 M CH3NH2 and 1.00 M CH3NH3Cl. Kb = 8.85 x 10-4 and what would happen after 35.0 mL of 0.45 M HNO3 is added to 250.0 mL of the buffer solution, what would the pH of the solution be after the HNO3(aq) is added?
Calcium oxalate monohydrate [Ca (O 2 CCO 2 )·H 2 O, also written as CaC 2 O 4 ·H 2 O] is a sparingly soluble salt that is the other major component of kidney stones [along with Ca 3 (PO 4) 2 ]. Its solubility in water at 25°C is 7.36 × 10 −4 g/100 mL. Calculate its Ksp. Given: solubility in g/100 mL.12/12/2023, 8:18:01 AM. To prepare 1000 mL of a 0.1 mol/L solution of Nitric acid we will need to dilute 6.37 mL of 70 % HNO3 to a final volume with deionized (distilled) water. Transfer the prepared solution to a clean, dry storage bottle and label it. Never store solutions in a volumetric flask. All chemicals that you are unfamiliar with
