When is a substance considered a strong acid? If it is highly corrosive false If it can corrode or melt anything false If it has a negative pH false If most of its components dissociate in water true Single What is the strongest possible base that can exist in an aqueous solution? OH- true O2- false Cl- false NH₄₊ false Single Which of the following acids will have a conjugate base when they undergo dissociation? ascorbic acid true sulfuric acid false nitric acid false all of the above false Single Suppose you have four relatively weak acids, each with a different Ka. Which substance is the strongest acid? The one with the lowest Ka. false The one with the highest Ka. true The one with the Ka equal to the ionization constant of water false The one with the Ka equal to the maximum pH possible. false Single What is the conjugate base formed by the dissociation of nitrous acid? nitrogen false nitrogen oxide false nitrogen dioxide true It will produce no conjugate base false Single The anion contributor of a certain salt is a weak acid. What is true about its cation contributor if the dissolution of this salt produces a solution that has a pH less than seven? The salt’s cation contributor is a strong acid true The salt’s cation contributor is a strong base false The salt’s cation contributor is a weak acid false The salt’s cation contributor is a weak base false Single What color will be produced when you put drops of thymol blue in a basic solution that was initially colorless? The solution will remain colorless false blue false yellow true red false Single What do you call the point in the titration curve that indicates that a solution already has an equal concentration of the acid and base? endpoint false turning point false critical point false equivalence point true Single What do you call the substance whose pH is being determined in a titration experiment? analyte true titrant false buffer false control solution false Single Strong bases are also strong electrolytes. What does this mean? Strong bases produce plenty of free ions true Strong bases require electricity to form false All strong bases are Lewis bases false Strong bases can separate water into H and O atoms false Single
