which methods will help you properly identify ph with indicator paper? check all that apply. set a piece of ph paper in front of each solution before testing to keep organized. dip the ph paper into each test tube and lay it on the table to let it change color. use a transfer pipet to remove a few drops from the solution to drop onto the paper. wait a minute or so before reading color. use the same piece of indicator paper for each solution to conserve paper.
Answer
Brief Explanations:
- Setting pH - paper in front of each solution helps with organization.
- Dipping pH - paper into the solution can contaminate it, so using a transfer pipet to drop a few drops onto the paper is better.
- Waiting a minute for the color to fully develop is necessary for an accurate reading. Using the same piece of paper for each solution will give inaccurate results as the paper has already reacted with the first solution.
Answer:
- Set a piece of pH paper in front of each solution before testing to keep organized.
- Use a transfer pipet to remove a few drops from the solution to drop onto the paper.
- Wait a minute or so before reading color.
