Dissolving one mole of each of the oxoacids HNO2, HClO4, H2CO3, and H3PO4 in 2.0 L of distilled water results in solutions with different pH values. Arrange these acid solutions from the one with the highest pH to the one with the lowest pH.
(A)HNO2 > HClO4 > H2CO3 > H3PO4 (B)HClO4 > HNO2 > H2CO3 > H3PO4 (C)H2CO3 > H3PO4 > HNO2 > HClO4 (D)H2CO3 > HNO2 > HClO4 > H3PO4
