The correct answer is (C) : Visualisation agent as a component of mobile phase.
The function of mobile phase is to carry the components present on TLC.
Let a line passing through the point $ (4,1,0) $ intersect the line $ L_1: \frac{x - 1}{2} = \frac{y - 2}{3} = \frac{z - 3}{4} $ at the point $ A(\alpha, \beta, \gamma) $ and the line $ L_2: x - 6 = y = -z + 4 $ at the point $ B(a, b, c) $. Then $ \begin{vmatrix} 1 & 0 & 1 \\ \alpha & \beta & \gamma \\ a & b & c \end{vmatrix} \text{ is equal to} $
Resonance in X$_2$Y can be represented as
The enthalpy of formation of X$_2$Y is 80 kJ mol$^{-1}$, and the magnitude of resonance energy of X$_2$Y is:
Qualitative Analysis involves the systematic identification of ions present in a mixture. It focuses on the properties and reactions of ions, particularly cations. The process begins with the systematic analysis of cations, where precipitation reactions are utilized to sequentially remove cations from a mixture. Students learn to recognize characteristic reactions and observe precipitates, helping identify specific ions.

In the context of salt analysis, students employ various techniques to identify cations and anions in inorganic salts. This step-by-step process aids in understanding the composition of the given salts. Additionally, qualitative chemical analysis explores the subjective investigation of substances, examining their chemical properties.
