Answer: acid; acidic
Explanation:
You have a glass of pure water and add acidic lemon juice to it. This means that you are adding ACID to it, and the solution will become ACIDIC.
Pure water has a pH value of 7
Lemon juice has a pH value less than 7 i.e acidic
Therefore, addition of lemon juice to pure water will drop the latter pH from 7 to form a final solution that is ACIDIC.
bacteria break down dead organisms which provide nutrients for the soil, therefore contributing to plant growth.

Answer: I would usually try my BEST to get help from yt videos. I recommend using yt that give the most kindergarten type speaking technique, this is really weird to say but it helps just incase you can be stressed out about the words being given by teachers in Chemistry. And I recommend writing down the notes when they explain as well. Hope this helps!
It can happen if acid or base is weak. This is because of hydrolyses of the salts that are formed in this reactions.
When acid is weak, and base is strong, the pH at the equivalent point is going to be basic.
If base is weak and acid strong the pH is going to be acidic.
