How many millimoles of HNO3 are present at the start of a titration?
The number of millimoles of HNO3 present at the start of a titration will depend on the initial concentration and volume of the HNO3 solution. To calculate millimoles, you can multiply the concentration of HNO3 in moles per liter by the volume of the solution in liters.
What is the concentration of HNO3 in a solution with pH3.4?
The concentration of HNO3 in a solution with pH 3.4 is approximately 3.98 x 10^-4 M. This is calculated using the formula pH = -log[H+], where [H+] is the hydrogen ion concentration in mol/L. For nitric acid (HNO3), one mole of HNO3 produces one mole of H+ in solution.
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 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 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.
Which substance increase h ion concentration in a solution?
acids such as HCl, H2SO4 HNO3 etc
What is HNO3 in water?
HNO3 does not react with water.It become diluted with water.
What is the molarity of nitric acid?
The molarity of nitric acid, HNO3, can vary depending on the concentration of the solution. For example, a 1 M solution of nitric acid would contain 1 mole of HNO3 per liter of solution. It is important to know the concentration or volume of the solution to determine the molarity of nitric acid.
What does 15 M HNO3 mean?
15 M HNO3 indicates a solution of nitric acid with a concentration of 15 moles per liter. This solution is highly acidic and can be used for various chemical reactions and laboratory purposes. The M signifies molarity, a measurement of concentration.
Why using two mole concentration sulfuric acid in preparation of nitrobenzene?
2H2SO4 + HNO3 → 2HSO4- + NO2+ + H3O+
What is the pH of a 0.01 M solution of the acid HNO3 in water?
- log(0.01 M HNO3) = 2 pH =====
A sample of the compound prepared in this experiment weighing 0.1021 g is dissolved in HNO?
To calculate the concentration of the sample, you need to know the volume of HNO3 used to dissolve it. Once you have that information, you can use the formula: concentration (mol/L) = mass of sample (g) / molar mass of compound (g/mol) / volume of HNO3 (L).
