Question
The pH probe/meter uses following equations:
Ecell = L + 0.0592 log a1 = L - 0.0592 pH
Where L = L1 + EAg/AgCI + Easy= constants
L1 = - 0.0592 log a2
a1 = activity of analyte solution a2 = activity of internal solution
How will measured pH value be affected vs “real” pH if HCl in pH electrode, became 0.15M instead of 0.1M ?
a.impact can not be determined
b.measured pH is higher than "real" pH.
c.measured pH is lower than "real" pH.
d.measured pH is same as "real" pH.
