Is quinine acidic or basic

Answer 1

Basic

"is alkaline to litmus, but not to phenolphthalein. Its solution in diluted sulphuric acid has a strong blue fluorescence, perceptible 1 in 200,000, which is destroyed by the halogen acids, hyposulphites, and other substances. Quinine is a strong base with an alkaline reaction in aqueous and alcoholic solutions, neutralising the strongest acids, forming neutral and acid salts, which for the most part crystallise well, their solutions tasting intensely bitter."
