Conjugate acid/base practice
Questions:
1. What is the conjugate base of HF?
2. What is the conjugate acid of Br-?
3. In the reaction
H2PO4- + H2O = H3PO4 + OH-
what is the base and its conjugate acid?
4. In the reaction
HNO2 + H2O = H3O+ + NO2-
what is the acid and its conjugate base?
Solutions:
1. F- (subtract an H+ ion)
2. HBr (add an H+ ion)
3. H2PO4 and H3PO4. They differ by one H+ ion, which is added to the conjugate acid.
4. HNO2 and NO2-. They differ by one H+ ion, which is subtracted from the acid.
