Acids and Bases. Acid- a substance that produces hydrogen ions (H + ) in a water solution. Taste sour Corrosive. Litmus paper in acids will turn/stay red. When an acid dissolves in water, H + ions interact with water molecules to form hydronium ions H 3 0 +. Common Acids - PowerPoint PPT Presentation
