Web2.3.1.2 Classical syntheses. Historical syntheses of perovskites are based on the ceramic and coprecipitation methods. The ceramic approach is a very simple thermal method, in which the precursors of the metal cations are ground, mixed, and calcined several times at temperatures above 1000°C, to ensure decomposition, solid-solid ion diffusion ... Web27 dec. 2024 · 1. To acidify the sample, add a few drops of dilute hydrochloric acid (HCl) to the sample. 2. Then, add a few drops of dilute barium chloride (BaCl 2) solution to the sample. 3. If sulfate ions are present in the solution, a white precipitate of barium sulfate (BaSO 4) will form. The reaction is: Ba²⁺ (aq) + SO 4 ²⁻ (aq) → BaSO 4 (s ...
