The following cell is used for measuring the partial pressure of oxygen at 700oC.
(Pt) Cu2Cu20 / 0.85 ZrO2 - 0.l5 CaO / O2 (Pt)
Knowing that conduction through the solid electrolyte (calcia stabilized zirconia) is attributed to the O-2 ions, derive the equation relating the cell e.m.f. to the partial pressure of oxygen. Use data from the Chemical Thermodynamic Properties.

As electron moves away from the nucleus, its potential energy: (1) Increases (2) Decreases (3) Remains constant (4) None of these Ans: Increases
how to calculate pH value?
Factors affecting TLC
When an electron jumps from L to K shell: (1) Energy is absorbed (2) Energy is released (3) Energy is sometimes absorbed and sometimes released (4) Energy is nei
unit of ell constant .
Radioanalytical methods: Radioanalytical methods using radiotracers and activation analysis are more sensitive and specific because of ease of detection of nuclear radiation.
