If nitric acid (HNO3) is added to water, it decreases the concentration of hydroxide ions in solution. This is because nitric acid semi-strongly dissociates in water, following this chemical reaction:
HNO3(aq) + H2O(l)-->NO3-(aq) + H3O+(aq)
The hydronium ions that are created in this reaction then react quickly with the hydroxide ions in the water, as shown in this chemical equation:
H3O+(aq) +OH-(aq) --> 2H2O(l)
This results in fewer hydroxide ions existing in solution.
HNO3 is an acid.So pH will be dropped.
It should change
no. water just dilutes the acid but the PH will not change unless an acid or alkali is added
increase
the pH will decrease slightly as oxalic acid is a weak acid.
- log(0.01 M HNO3) = 2 pH =====
It should change
The pH deccrease.

Nothing because water is the only substance which has a PH of 7. Anything added to the water would change the PH unless you added pure water to it.
The water pH will change when substances are added to water. If the pH is more than 7 it makes the water basic and if it is less than 7 the water is acidic.
Not much change, ATP is neutral
increase
the pH will decrease slightly as oxalic acid is a weak acid.
- log(0.01 M HNO3) = 2 pH =====
pH = - log10 [H+], where [H+] is the molar concentration of hydrogen ions. HNO3 is a strong acid and dissociates completely in water so a 5 M solution of HNO3 would have a concentration of hydrogen ions of 5M also. So, pH = -log10[5] = -0.699 which indicates an extremely strong acid.
Because the Photosynthesis added carbon dioxide to the water
The pH of water increase.
