Acids or Weak Bases increases the concentration of HA by an amount equal to [
OH - ] . Thus the molar concentration of HA is given by [ HA ] = Fra – [ H3O + ] + [
OH - ] ( 9 - 3 ) Similarly , the reaction in Equation 9 - 1 increases ( A - ] by an ...

At this point the solution contains a large amount of carbonic acid and a small
amount of unreacted hydrogen carbonate . Boiling effectively destroys this buffer
by eliminating the carbonic acid : H2CO3 → CO2 ( g ) + H2O As a result , the ...

3 % moisture in excess of the stoichiometric amount . For all but the most
exacting work this excess is sufficiently reproducible to permit use of a corrected
weight for the salt in the direct preparation of a standard solution . If necessary ,
