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.

∙ 13y agoHNO3 is a strong mono-protic acid.
This means it fully ionises to NO3- and H+
Therefore the concentration of H+ = 1.0M
pH = -log[H+] = -log(1.0) = 0
pH = 0

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?
To calculate the pH of the solution, you first need to determine the concentration of nitric acid in moles per liter. Then you can calculate the pH using the formula for pH: pH = -log[H+]. Given the amount of nitric acid and volume of water, you can find the pH.
What is the pH and pOH of a 0.0067M HON3 solution?
Since HNO3 is a strong acid, it completely dissociates in solution. HNO3 -> H+ + NO3-. Therefore, the concentration of H+ ions is the same as the concentration of the HNO3 solution, 0.0067M. pH = -log[H+] = -log(0.0067) ≈ 2.18. pOH = 14 - pH ≈ 11.82.
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 a 1.6 10-3 M HNO3 solution?
The pH of a 1.6x10^-3 M HNO3 solution is approximately 2.8. This is calculated by taking the negative logarithm (base 10) of the concentration of the hydrogen ions in the solution.

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 2M hcl?
The pH of a 2M HCl solution is around 0. This is because HCl is a strong acid that dissociates completely in water to produce H+ ions, leading to a highly acidic solution.

The pH of a 1.6x10^-3 M HNO3 solution is approximately 2.8. This is calculated by taking the negative logarithm (base 10) of the concentration of the hydrogen ions in the solution.
Why HNO3 is called a strong acid since its pH is less than that of H3O?
the lower the pH the stronger the acid
What is the molarity of a strong acid solution with a pH of 2?
The molarity of a strong acid solution with a pH of 2 is 0.01 M. This is because the pH of a solution is equal to the negative logarithm of the hydrogen ion concentration ([H+]). In this case, the [H+] is 0.01 M.
What is the fix pH of HCL and HNO3?
The fixed pH of hydrochloric acid (HCl) is around 0, while the fixed pH of nitric acid (HNO3) is around -1. This is due to their strong acidity, which results in a low pH value.
How much 2.5 molarity of HNO3 is required to react the CaCO3?
This depends on the mass of calcium carbonate.
What is the pH of HNO3?
The pH of HNO3 is about 0.1. It is a strong acid, and when dissolved in water, it completely dissociates into H+ and NO3- ions. This high concentration of H+ ions results in a low pH value close to zero.
What is hydrogen ion concentration of 0.5 HNO3?
A 0.5 M solution of HNO3 will have a hydrogen ion concentration of 0.5 moles per liter. This is because each molecule of HNO3 ionizes to produce one hydrogen ion in solution.
What substances have the highest pH?
Concentrated bases (more than 2M/L) as sodium hydroxide for example.
