WebA formic acid solution has a pH of 3.40. Part A Which of the following substances will raise the pH of the solution upon addition? Check all that apply. Naci OHCI O NaCHO, KNO3 This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer WebSince HCl is a strong acid, Ka is immeasurably large and Kb ≈ 0 (chloride ions don’t undergo appreciable hydrolysis). Thus, dissolving ammonium chloride in water yields a solution of weak acid cations ( NH 4 +) and inert anions (Cl − ), resulting in an acidic solution.
