Answer:
The correct answer is - option 1. the solution is acidic.
Step-by-step explanation:
The pH is a scale to measure or check the acidity or basicity of an aqueous solution. The lower values on the pH scale indicate the acidity of the solution as on the pH bar 0 indicating the highest acidic value and the higher value indicates the alkaline or basic value of the solution and 14 indicating the highest alkaline. The pH of water is 7 which is a neutral condition.
Therefore, the pH of a solution with 5.5 on pH solution represents the acidic property of the solution, however, it is slightly acidic as it is near the neutral value.
