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.
What is the pH of a 1.45M HNO3 solution?
The pH of a 1.45M HNO3 solution is approximately 0.14. This is because nitric acid is a strong acid that dissociates completely in water to yield H+ ions.
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?
the pH level of salt added to water is 7.5-7.8... almost neutral!
Will NH3 increase decrease or no change in the pH when added to water?
The pH deccrease.
Does the pH of ethanol change if water is added?

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

the pH level of salt added to water is 7.5-7.8... almost neutral!
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.
What is the pH of a solution that contains 1.32 grams of nitric acid dissolved in 750 milliters of water?
Two steps. Find molarity of nitric acid and need moles HNO3.Then find pH. 1.32 grams HNO3 (1 mole HNO3/63.018 grams) = 0.020946 moles nitric acid ------------------------------------- Molarity = moles of solute/Liters of solution ( 750 milliliters = 0.750 Liters ) Molarity = 0.020946 moles HNO3/0.750 Liters = 0.027928 M HNO3 ----------------------------------finally, - log(0.027928 M HNO3) = 1.55 pH ==========( could call it 1.6 pH )
What is the pH of 2M HNO3?
The pH of a 2M HNO3 solution is approximately 0. This is because nitric acid (HNO3) is a strong acid that fully dissociates in water to release H+ ions, resulting in a highly acidic solution with a low pH value.
Why did PH change during the light experiment?
Because the Photosynthesis added carbon dioxide to the water
