Answer : The concentration of [CoCl₄]²⁻ is,
Explanation :
Using Beer-Lambert's law :
where,
A = absorbance of solution = 0.935
C = concentration of solution = ?
l = path length = 0.71 cm
= molar absorptivity coefficient =
Now put all the given values in the above formula, we get:
Therefore, the concentration of [CoCl₄]²⁻ is,
