Acid Base Chemistry

Arrehenius Acids
- Produce H+ ions in water
- Have a sour taste
- Turn litmus red
HCl-->H+ + Cl-
Arrhenius Bases
- Produce OH- ions in water
- Are soapy and slippery
- Taste bitter or chalky
- Turn litmus blue
Bronsted-Lowry Acids

Donate a proton (H+)

HCl + H2O <-> H3O+ + Cl-

HCl is the acid that donates H+
Bronsted-Lowry Bases

Accept a proton (H+)

NH3 + H2O <-> NH4+ + OH-

NH3 is the base that accepts H+
Conjugate Acid-Base Pairs
\/----------------\/
- HA + B <-> A- + BH+
- /\-----------------/\
- Pairs are related by the loss and gain of H+
- 1 pair occurs in fwd direction other in rev
Strong Acids
- HCLO4 ---> CB = CLO4-
- H2SO4 ---> CB = HSO4
- HI ---> CB = I-
- HBr ---> CB = Br-
- HCl ---> CB = Cl-
- HNO3 ---> CB = NO3-
Strong Bases
- Group 1A (alkali) and 2B (alkaline) Hydroxides
- i.e.;
- LiOH
- NaOH
- KOH
- Mg(OH)2
- Ca(OH)2
pH at equivalent point
