Question

1. in gatorade, there is sodium and potassium. they are both ions with the following chemical symbols: na+ and k+. they are examples of: a. anions b. onions c. electrolytes d. protons

Explanation:

• Option a: Anions are negatively charged ions, while \( \text{Na}^+ \) and \( \text{K}^+ \) are positively charged, so a is incorrect.
• Option b: "Onions" are a type of vegetable, not related to chemical ions, so b is incorrect.
• Option c: Electrolytes are substances that dissociate into ions (like \( \text{Na}^+ \) and \( \text{K}^+ \)) in solution and conduct electricity. Sodium and potassium ions in Gatorade act as electrolytes, so c is correct.
• Option d: Protons are subatomic particles, not the same as these ions, so d is incorrect.

Answer:

c. Electrolytes
