Answer: If the pH is less than 7, the solution is acidic.
If the pH is 7, the solution is neutral.
If the pH is greater than 7, the solution is basic.
Explanation: The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic.
Acids are substances that provide hydrogen ions (H+) when dissolved in water. Examples of acidic solutions include vinegar (acetic acid), lemon juice (citric acid), and battery acid (sulfuric acid).
Bases are substances that provide hydroxide ions (OH-) when dissolved in water. Examples of basic solutions include bleach (sodium hypochlorite), ammonia, and lye (sodium hydroxide).
Neutral solutions have a pH of 7 and are neither acidic nor basic. Pure water has a pH of 7.
Hope this helps, and have a great day!
