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.

Does the pH of ethanol change if water is added?
Yes, adding water to ethanol will change its pH. Ethanol is a neutral compound with a pH of around 7. However, adding water will dilute the ethanol, potentially changing its pH depending on the amount of water added and the initial concentration of the ethanol solution.
Does water change the pH level of vinegar?
Yes, water can dilute vinegar and change its pH level slightly. Adding water to vinegar will decrease its acidity, thus raising the pH level. However, the change may be minimal depending on the amount of water added.
Will the pH change when an alkali is added to an acid?
Yes, the pH will change when an alkali is added to an acid. The addition of an alkali to an acid will result in the neutralization reaction, forming water and salt. This reaction will change the pH towards being more neutral.
What is the pH level of salt added to water?
Salt added to water does not significantly change the pH level. The pH of water, which is neutral, remains close to 7 even after adding salt. The effect of salt on the pH of water is minimal.
What is the pH of 15 mL of 0.0045 M HNO3?
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.
Does the pH of ethanol change if water is added?
Yes, adding water to ethanol will change its pH. Ethanol is a neutral compound with a pH of around 7. However, adding water will dilute the ethanol, potentially changing its pH depending on the amount of water added and the initial concentration of the ethanol solution.
Will NH3 increase decrease or no change in the pH when added to water?
The pH deccrease.
Does water change the pH level of vinegar?
Yes, water can dilute vinegar and change its pH level slightly. Adding water to vinegar will decrease its acidity, thus raising the pH level. However, the change may be minimal depending on the amount of water added.
What substance forms a solution in water with a PH of 7?
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.
Why did the water pH change?
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.
What is the pH of water when ATP is added?
Not much change, ATP is neutral
Will NaOH increase decrease or no change in pH when added to water?
NaOH will increase the pH of water because it is a strong base that dissociates in water to form OH- ions, which react with water to produce more hydroxide ions, shifting the solution towards a basic pH.
Will H2C2O4 increase decrease or no change in the pH when added to water?
the pH will decrease slightly as oxalic acid is a weak acid.
What is the pH of a 0.01 M solution of the acid HNO3 in water?
The pH of a 0.01 M solution of HNO3 would be around 2. Negative logarithm of the hydrogen ion concentration (10^-2) will give a pH value of 2 for the solution.
What is the pH of 15 mL of 0.0045 M HNO3?
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.
Why did PH change during the light experiment?
Because the Photosynthesis added carbon dioxide to the water
When KOH is added to water what does the pH of the water solution do?
The pH of water increase.
