• Write a balanced equation showing how the following substances behave as acids in water and identify the conjugate acid-base pairs.

  HNO3 HCO3- H3PO4 H2PO4-
  

• HNO3(aq) + H2O(l) ? H3O+ (aq) + NO3-(aq)

• HCO3-(aq) + H2O(l) ? H3O+ (aq) + CO32-(aq)

• H3PO4(aq) + H2O(l) ? H3O+ (aq) + H2PO4-(aq)

• H2PO4-(aq) + H2O(l) ? H3O+ (aq) + HPO42-(aq)

• acid 1 base 2 acid 2 base 1
