Webalkali metal, any of the six chemical elements that make up Group 1 (Ia) of the periodic table —namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids ). WebDec 27, 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 ...
