QUESTION #35 Kohlrausch's Law
Given below are two statements: Statement I: Mohr's salt is composed of only three types of ions-ferrous, ammonium and sulphate. Statement II: If the molar conductance at infinite dilution of ferrous, ammonium and sulphate ions are mathbfx_1, mathbfx_2 and mathbfx_3 mathrmS\ cm^2\ mathrmmol^-1, respectively then the molar conductance for Mohr's salt solution at infinite dilution would be given by mathbfx_1 + mathbfx_2 + 2mathbfx_3. In the light of the given statements, choose the correct answer from the options given below:

QUESTION #48 Nernst Equation
1 Faraday electricity was passed through mathrmCu^2+ (1.5 M, 1 L)/Cu and 0.1 Faraday was passed through mathrmAg^+ (0.2 M, 1 L)/Ag electrolytic cells. After this, the two cells were connected as shown below to make an electrochemical cell. The emf of the cell thus formed at 298 K is ______ V. {{IMG1}} Given: mathrmE_mathrmCu^2+/mathrmCu^circ = 0.34 mathrm~V mathrmE_mathrmAg^+/mathrmAg^circ = 0.8 mathrm~V frac2.303RTF = 0.06 mathrm~V
