Answer:
Negative gravitropism
Explanation:
Negative gravitropism is the growth of a plant away from gravity.
Vitamin C is a water-soluble vitamin that is mainly found in fruits and vegetables. Orange juice is one of the most recognized sources of vitamin C. Vitamin C is an unstable vitamin and it oxidizes when it comes into contact with air. If Vitamin C content in the fruit juices are exposed for one day, the fruit juices will come in contact with oxygen and this would result in complete loss of vitamin C. Consumption of the uncovered fruit juices will not benefit the body anymore, because the vitamin C cannot be retained due to its exposure to air.
The pH range for an acid is pH < 7 with the strength increasing downwards so an acid with pH 1 is much stronger than one with 6.
The range for a Base is pH > 7 with the strength increasing with number thus a substance with pH 14 is much stronger than a substance of pH 8.
With that said, <span>
A solution with a pH of 13 would be a
STRONG BASE (alkali since it is in solution).
Additional: I attached a pH scale so that at any point in time you can check the pH scale and match it to the substance given and tell whether it is a strong or weak base or acid.
