Answer:
sulphuric is a strong acid
Explanation:
Sulphuric is a strong acid because it completely ionises in water while acetic acid partially ionises in water
The experimental control is the standard used as a comparison for the experimental groups.
For example, you may be trying to find out how different types of disinfectants affect bacterial growth. The control group would receive <em>no</em> disinfectant whereas the experimental groups would be the ones on which the disinfectants were tested.
Hope this makes sense!
