Schiff's reagent test is a qualitative test to detect aldehydes, giving a pink/magenta color due to the formation of a complex.
Schiff's reagent
Step 1: Schiff’s reagent is used to distinguish between aldehydes and ketones. Aldehydes react with Schiff’s reagent to give a pink color, whereas ketones do not react. Since acetaldehyde is an aldehyde and acetone is a ketone, Schiff’s reagent can differentiate between them
Find the values of \( x, y, z \) if the matrix \( A \) satisfies the equation \( A^T A = I \), where
\[ A = \begin{bmatrix} 0 & 2y & z \\ x & y & -z \\ x & -y & z \end{bmatrix} \]
