When liquid 'A' is treated with a freshly prepared ammoniacal silver nitrate solution it gives bright silver mirror. The liquid forms a white crystalline solid on treatment with sodium hydrogen sulphate. Liquid 'B' also forms a white crystalline solid with sodium hydrogen sulphate. but it does not give test with ammoniacal silver nitrate. Which of the two liquids is aldehyde? Write the chemical equations of these reactions also.

To solve the problem, we need to analyze the information provided about the two liquids, A and B, and determine which one is an aldehyde. ### Step 1: Analyze Liquid A - **Observation**: Liquid A gives a bright silver mirror when treated with freshly prepared ammoniacal silver nitrate solution (Tollens' reagent). - **Conclusion**: The silver mirror test is characteristic of aldehydes. Therefore, Liquid A is likely an aldehyde. **Chemical Equation for Liquid A with Tollens' Reagent**: \[ RCHO + 2[Ag(NH_3)_2]^+ \rightarrow RCOOH + 2Ag + 2NH_3 \] ...
