Which one of the following is a correct acid to conjugate base pair? Acid Conjugate Base
HCl is an Arrhenius acid because it produces H+ions in aqueous solution. 1. NH4​+is a Bronsted-Lowry acid because it donates a proton to water. 1. NaCl is basic salt I and III only II and IV only All are true. I only I, II and III only
Which statement about H3​PO4​ and/or H2​SO4​ is correct? None of the above are correct. They both have one hydrogen atom They are both produce strong conjugate bases. they are both strong acids.
Which of the following is TRUE? None of the above are true. The equivalence point is where the moles of acid equals the moles of its conjugate base for any acid-base titration. The point where the indicator changes color identifies endpoint. At the equivalence point, the pH is always 7. An indicator is not pH sensitive.
What is a true statement about indicators. Indicators are a basic salt solution that forms a precipitate ate the end point They are a molecular compound like a sugar and are only sensitive to changes in volume at constant ph. They are a neutral compound and are driven by the formation of a precipitate They are a weak acid and sensitive to changes in pH by the Le Chatlier Principle
