Question:
A cyanide ion-selective electrode obeys the equation
E = constant - 0.059 16 log[CN-]
The potential was - 0.230 V when the electrode was immersed in 1.00 mM NaCN.
(a) Evaluate the constant in the equation.
(b) Using the result from part (a), find [CN-] if E= - 0.300 V.
(c) Without using the constant from part (a), find [CN-] if E = - 0.300 V.
