Citric acid is used as a preservative and flavor enhancer in the food industry. - **Acetic acid**: found in vinegar. Acetic acid is commonly used in cooking and as a cleaning agent. - **Hydrochloric acid**: found in stomach acid. Hydrochloric acid plays a crucial role in digestion. ### What are Bases? Bases, on the other hand, are chemical substances that have a bitter taste and feel slippery to the touch. They are typically characterized by their ability to accept a hydrogen ion (H+). #### Examples of Common Bases: - **Sodium hydroxide**: found in soap and cleaning agents. Sodium hydroxide is a strong base used for cleaning surfaces and removing grease. - **Calcium carbonate**: found in limestone and chalk. Calcium carbonate is used in construction and as a dietary supplement. - **Ammonia**: found in cleaning products and fertilizers.
