Acid-base Equilibrium

Question
3 out of 10
 

Which of the following is not a polyprotic acid?

A H2SO4
B H2PO4
C H3AsO4
D None of the above
Ans. D An acid which can furnish more than one proton per molecule of the acid is called a "polyprotic acid." Choices A, B and C are all polyprotic acids. So the reasonable choice is 'one of the above.'Note that the question asked for an acid which is not a polyprotic acid. You should make a habit of underlining or circling key words in the question, especially when the question stem contains words such as "not, except, increasing, decreasing."
