Lila test the ph up for solutions which solution should she identify as being a base solution a solution d solution c or solution base
Lila should identify solution d as being a base solution.
To identify the base solution, Lila can perform a pH test using an indicator or a pH meter. Here are the step-by-step instructions for performing the pH test:
1. Gather the solutions that need to be tested: solution A, solution B, solution C, and solution D.
2. Prepare the pH testing tool: If using an indicator, prepare the indicator solution according to the manufacturer's instructions. If using a pH meter, ensure it is calibrated and functioning properly.
3. Rinse the testing tool: Clean the pH testing tool with distilled water to remove any residue from previous tests. This ensures accurate results.
4. Take a small sample from solution A using a dropper or pipette.
5. Add a few drops of the indicator solution to the sample from solution A. If using a pH meter, dip the electrode into the sample.
6. Observe the color change or pH reading: Look for a characteristic color change on the color chart provided with the indicator. If using a pH meter, note the numerical pH reading displayed.
7. Repeat steps 4-6 for solution B, solution C, and solution D, using fresh samples each time.
8. Compare the results: Look for the solution that displays characteristics of a base. In general, bases have a pH value greater than 7 or show a blue or purple color with certain indicators (such as phenolphthalein or litmus paper).
Based on the results obtained, Lila can identify the solution that displays the characteristics of a base.
To identify the base solution, Lila can test the pH of the given solutions. pH is a scale used to measure the acidity or basicity of a solution, ranging from 0 to 14. A pH value less than 7 indicates an acidic solution, a pH of 7 indicates a neutral solution, and a pH greater than 7 indicates a basic (alkaline) solution.
Lila can use pH testing strips or a pH meter to measure the pH of each solution. Here is the process she can follow:
1. Start by dipping a pH testing strip into solution A or using a pH meter probe to measure the pH. Compare the color of the strip with the provided color chart (if using pH strips) or read the pH value on the meter display (if using a pH meter).
2. If the pH of solution A is less than 7, it is an acidic solution.
3. Repeat the process of measuring the pH for solutions B, C, and D, following the same steps mentioned above.
4. If the pH of solution B, C, or D is greater than 7, then it is a basic (alkaline) solution.
Therefore, Lila should identify the solution with a pH greater than 7 as the base solution.
