NH3= 20mL of 0.1M This is a buffer solution, A: Glacial acetic acid is purest form of acetic acid in which anhydrous form or undiluted form of, A: According to the question we have the reaction for the piperidine (C5H10NH) and iodic acid (HIO3):-, A: Since the exact question is not mentioned we only answer the first question. HC2H3O2(aq) + H2O(l) <-----> H3O+(aq) + C2H3O2-(aq) Ka = 1.8 x 10-5 What is the hydronium ion concentration ([H3O+]) in a 2.88 M HC2H3O2 solution? How many grams of NaC2H3O2 must be This order corresponds to decreasing strength of the conjugate base or increasing values of \(pK_b\). Substituting the \(pK_a\) and solving for the \(pK_b\).
