Acids and Bases

Acids are substances that can donate a proton and have a sour taste. They turn litmus paper red and react with metals to produce hydrogen gas. Examples include hydrochloric acid and sulfuric acid. Bases can accept a proton or donate hydroxide ions. They have a bitter taste, feel slippery, and turn litmus paper blue. Examples include sodium hydroxide and ammonia. Good morning, everyone. Today, we are going to learn about acids and bases. Acids are the substances that can donate a proton to another substance. They are characterized by their foretaste, ability to turn litmus paper to red, and ability to react with metals to produce hydrogen gas. Examples, hydrochloric acid, sulfuric acid, and citric acid. Bases are substances that can accept a proton from another substance, or that can donate hydroxide ions. They typically have a bitter taste, feel slippery to the touch, and turn litmus paper blue. Examples, sodium hydroxide, ammonia, and magnesium hydroxide. Thank you.
