Aldehydes form red precipitate with Fehling solution of………

Explanation

**Step-by-Step Solution:**

1. **Understanding Fehling's Solution:**
- Fehling's solution is a chemical reagent used to test for the presence of aldehydes. It is composed of two solutions: Fehling's A (copper(II) sulfate solution) and Fehling's B (a mixture of sodium hydroxide and potassium sodium tartrate).

2. **Composition of Fehling's Solution:**
- Fehling's A contains copper(II) sulfate pentahydrate (CuSO₄·5H₂O).
- Fehling's B contains sodium hydroxide (NaOH) and potassium sodium tartrate (C₄H₄O₆·4H₂O).
