• what is an example of an acid? what was the ph?

• what is an example of a base? what was the ph?

• what ph values indicate:

basic _____________
acidic_____________
neutral solution___________

Explanation:

1. Example of an acid: Hydrochloric acid (HCl) is a common acid. Its pH is typically around 1 - 3 (depending on concentration).
2. Example of a base: Sodium hydroxide (NaOH) is a common base. Its pH is typically around 11 - 14 (depending on concentration).
3. pH values:

• Basic: pH > 7 (solutions with pH greater than 7 are basic, the higher the pH above 7, the more basic the solution).
• Acidic: pH < 7 (solutions with pH less than 7 are acidic, the lower the pH below 7, the more acidic the solution).
• Neutral solution: pH = 7 (pure water at 25°C has a pH of 7, indicating a neutral solution).

Answer:

• Example of an acid: Hydrochloric acid (HCl), pH ~1 - 3 (varies by concentration).
• Example of a base: Sodium hydroxide (NaOH), pH ~11 - 14 (varies by concentration).
• Basic: pH > 7; Acidic: pH < 7; Neutral solution: pH = 7.
