Document Summary

The naf will provide f- ions: a buffer solution resists change in ph when an acid or base is added to it, same mole ratio buffers works best. Henderson-hassel balch equation: equation is based on the assumption that the initial concentration of the acid and base component of the buffer equal the equilibrium concentrations (this assumption will always hold true for any decent buffer) [acid]=[conjugate base]; ph of buffer=pka ph of the buffer depends on the ratio of [a-]/[ha: this equation can only be used to solve for the ph of buffer solutions. The acid ha in the buffer neutralizes the added base and is converted to. The base a- in the buffer neutralizes the added acid and is converted to. Indicators, equivalence point and endpoint: titrant: will be strong acid or base; analyte: will be acid (if titrant is a base) or base (if.
