Lily test the pH of four solutions which solution should she identify as being a base and the solution says a the pH is to be pH is 5C the pH is seven and D the pH is nine so with the answer be solution C or solution or solution C

Answer 1

To identify which solution is a base based on pH values, we can use the scale of pH:

• A pH of 7 is neutral (like pure water).
• A pH less than 7 indicates an acidic solution.
• A pH greater than 7 indicates a basic (alkaline) solution.

Given the following pH values:

• Solution A: pH 5 (acidic)
• Solution B: pH 7 (neutral)
• Solution C: pH 7 (neutral)
• Solution D: pH 9 (basic)

The only solution that is identified as a base is Solution D with a pH of 9.

So, the answer is Solution D.
