Prepare a 1% copper sulfate solution. To make this solution, weigh 1 gram of copper sulfate (CuSO4 ·5H2O), dissolve in a small amount of distilled water in a 100 ml volumetric flask and bring to volume. Label this as 1% copper sulfate solution.
Answer:
Neutral solution, pH of 7.
Explanation:
Red cabbage is a natural indicator which gives red color when an acid is added, green color when a base is added and <u>it gives blue color when a neutral solution is added. </u>
<u>Given that when some red cabbage indicator is added to a solution , it turns blue which means that the solution is a neutral solution. Neutral solution have a pH of 7.</u>
More the number of turns, more will be the magnetic field produced.
Hence wire A will have magnetic field greater than wire B.
Hope this helps!
