- How many moles of HNO3 are present if 0.116 mol of Ba(OH)2 was needed to neutralize the acidsolution? Only typed solutionarrow_forwardThe pH of an aqueous solution at 25.0 °C is 7.85. What is the molarity of OH- in this solution? Input answer in exponential form, example, if the answer is 5.72x10-8, enter as 5.72e-8.arrow_forwardFor a weak acid, HA, with Ka = 7.51x10-3, what ratio of [A-] to [HA] is required to produce a pH of 3.897? Answer:arrow_forward
- Baseline Question: Calculate the pH of a 5.6x10-9M HCl aqueous solution. ANS: pH=6.99 Commentary: Since I know HCl is a strong acid and ionization is 100%, I thought I could find pH as -log(5.6x10-9), however my teacher said that was incorrect . She did a Kw=[OH-][H3O+] to find x. Use image below to see my work. The answer to the question is pH= 6.99. Actual Question:I want to know why we had to do an ICE table and find "x" (another H3O concentration) instead of -log(5.6x10-9).arrow_forwardWhich of the following can behave as Bronsted-Lowry bases in aqueous solution? NaOH NH3 H2SO4 HCO3- None of the Above Submit Answerarrow_forwardMagnesium reacts with sulfuric acid in a single displacement reaction. How manymilligrams of hydrogen gas can be produced from the reaction of 36.00 mL of a sulfuricacid solution with a pH of 1.731 and excess magnesium? answer in milligrams!!!arrow_forward
- If the H3O+ ion concentration in an aqueous solution at 25°C is measured as 8.97 x 10^-5 M, what is the pH of the solution? Report answer with two places past the decimal point.arrow_forwardWhat is the concentration (in M) of a barium hydroxide solution, if 10.0 mL is completely neutralized by 12.22 mL of 0.800 M HCl? (Answer to 3 significant figures.)arrow_forwardWhat is the pH of a 0.0100 M solution of analine (C6H5NH2) , a weak base. Kb= 4.0 x10-10 (ICE problem) Your answer should have 2 digits after the decimalarrow_forward
- Ka for acetic acid, CH3COOH, is 1.80×10-5.Ka for formic acid, HCOOH, is 1.80×10-4.Ka for nitrous acid, HNO2, is 4.50×10-4. What is the formula for the weakest conjugate base? Submit Answerarrow_forwardExercise 16.2 Calculate [H+] in a solution in which [OH]=2.0102M. Is this solution acidic, neutral, or basic?arrow_forwardQuestion: What is the pH of a 3.773.77×10−5×10-5 M solution of hydrochloric acid?arrow_forward
