a substance that turns blue litmus paper red, contains hydrogen atoms, and tastes sour is\na. a base.\nb. a metal.\nc. an acid.\nd. an indicator.\ne. a halogen.
Answer
Brief Explanations:
Acids turn blue litmus paper red, contain hydrogen - ions (and thus hydrogen atoms in a chemical sense), and often have a sour taste. Bases turn red litmus paper blue. Metals are elements with certain physical and chemical properties and don't match these acid - related characteristics. Indicators are substances that change color in response to the acidity or basicity of a solution, not the substances with the described properties themselves. Halogens are a group of elements in the periodic table and are not defined by these properties.
Answer:
C. an acid
