Answer:
In a neutral solution the concentration of hydrogen ions is equal to the concentration of hydroxide ions
Explanation:
When:
[H⁺] > [OH⁻] the pH is acid, so the solution is practically acid.
When
[H⁺] < [OH⁻], the pH is basic, so the solution is practically basic
In neutral solutions:
[H⁺] = [OH⁻], so the pH is neutral (7)
pH > 7 → BASIC SOLUTIONS
pH < 7 → ACID SOLUTION
Answer:
Answer:
B. It's dissociation is a reversible reaction
Explanation:
NH3 is a weak alkali that does not dissociate fully into its solution. Only parts of the ammonia takes part in the dissociation process.
NH3 + H20 —> NH4+ + OH-
This dissociation is reversible which means the reactants can be formed from the product gotten from the dissociation
It has a high pH due to its basic nature. It also has a Low concentration of H+ ions and not all the OH- ions are released.
Answer:
What are some things that might happen that can change our air so that it is not health for plants?
Explanation:
Air pollutants have a negative impact on plant growth, primarily through interfering with resource accumulation. Once leaves are in close contact with the atmosphere, many air pollutants, such as O3 and NOx, affect the metabolic function of the leaves and interfere with net carbon fixation by the plant canopy. Air pollutants that are first deposited on the soil, such as heavy metals, first affect the functioning of roots and interfere with soil resource capture by the plant.
