Final answer:
Acids and bases share properties such as the ability to conduct electricity due to being electrolytes and the potential to cause burns, but they differ in taste and reactions with metals.
Step-by-step explanation:
Both acids and bases share certain properties, but they also have characteristics that are unique to each. Acids are substances with a sour taste, such as the citric acid in lemons or acetic acid in vinegar. They can turn blue litmus paper red and react with certain metals to produce hydrogen gas. Bases, contrastingly, usually have a bitter taste and feel slippery due to their ability to react with fats to form soap-like structures; an example of this is sodium hydroxide.
Both acids and bases conduct electricity when dissolved in water, known as their property of being electrolytes. This is because both acidic and basic solutions contain ions that move to carry electric current. Also, both can cause burns depending on their concentration and the nature of the substance; for example, concentrated sulfuric acid and sodium hydroxide can both be very corrosive.
