Why is the emf of a cell measured with a voltmeter of very high resistance?

← All Quizzes

← A cell is written as M(s) mid M²⁺(aq) ∥ N⁺(aq) mid N(s). What does the double bar stand for, and which electrode is the cathode?The standard potentials are E°(Co²⁺/Co) = -0.28 V and E°(Ag⁺/Ag) = +0.80 V. What is the standard emf of the cell Co(s) mid Co²⁺(aq) ∥ Ag⁺(aq) mid Ag(s)? →
