Final answer:
Acids can be both physical and chemical properties, although not all acids are affected by other acids chemically.
Step-by-step explanation:
Acids can be classified as substances that release hydrogen ions (H+) in solution, while bases are substances that release hydroxide ions (OH-) in solution. Acids can be both physical and chemical properties. Physical properties of acids include their taste and the ability to conduct electricity, while chemical properties include their ability to react with other substances. It is important to note that not all acids are affected by other acids, which means they are not affected chemically.
