Question

Paper – 2020
61. A 0.1 M solution of compound A shows
50% transmittance when a cell of 1 cm
width is used at a, nm. Another 0.1 M
solution of compound B gives the optical
density value of 0.1761 using 1 cm cell
at 2, nm. What will be the transmittance
of a solution that is simultaneously 0.1 M
in A and 0.1 M in B using the same cell
and at the same wavelength ?
(log 20 = 1.301; log 30 = 1.4771;
log 50 = 1.699)
(a) 33.3%
(b) 50%
(c)
66.7%
(d)
70%​
