Question

In polarographic technique, a series of standard solutions containing the metal ions is prepared and the wave
heights are determined. The results obtained were as follows:

Cone, in mm dm-3
0.40, 0.80,
1.20.

Height in mm
28.0, 55.9, 83.9.

An unknown solution under exactly identical conditions gave a wave height of 42 mm. Calculate the
concentration of the metal ions in the unknown solution.


A. 0.60 mm
B. 1.0 mm
C. 0.5 mm
D. 1.02 mm​

Answer 1

Answer:

c 0.5 mm is the correct correct correct option hope it helps you have a nice day while I take care in
