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.
what is molality?
2Zns + 3O 2 ---------> 2ZnO + 2SO 2 ZnCO 3 -------------> ZnO + CO 2 ZnO +C ------> Zn +CO ZnO + CO -----------> Zn + C0 2
proper definition plz
whats a reversible cell
Q. Show properties of the Borax? Salts of boric acids are known as borates. As said earlier, hydrated borates occur naturally, e.g., borax, Na 2 B 6 0 11 . 5H 2 0, kernite, Na
20ml of water sample requires 15ml of 0.1mg/l sodium carbonate using phenolphthalein indicator. state the type of acidity and calculate the acidity
