What is the pH of a 10 8 M HNO3 solution?
∴pH=6.9586.
What is the pH of 10 4 M HNO3?
0.3
The pH of 4.0 × 10^-4M HNO3 solution is ( log 2 = 0.3 )
What is the pH of NH3?
pH of Ammonia One molecule of ammonia consists of one negatively-charged nitrogen ion and three positively-charged hydrogen ions, giving ammonia a chemical formula of NH3. The pH of standard ammonia is about 11.
How do you find the pH from molarity of HNO3?
1) Determine the pH of a 0.00340 M HNO3 solution. pH = -log[H+] = -log(0.00340) = 2.47 2) Determine the pOH of a 0.00340 M HNO3 solution. 3) Determine the pH of a 4.30 x 10-4 M NaOH solution.
What will be the pH of 10 8 M h2so4?
So pH=-log(12*10^(-8)) = 6.92 (approx.)
How do you calculate pH from pKb?
Calculation of the pH of a weak base:
- Find the [OH-] from the pKb value (in the same way as for weak acid type calculations)
- From the [OH-] find the pOH.
- Find the pH from: pOH + pH = 14.
What is the pH of 0.6 M hno3 solution?
0.222
The pH of 0.6 M Nitric acid is 0.222 which is a highly acidic solution.
How do you find the pH of HNO3 with concentration?
Therefore, you can say that the concentration of H+ ions in solution is the same as the concentration of the acid (molar concentration). So once you have that, you can use the pH formula to find the pH of the acid. pH = -log[H+] So if you have .15 M HNO3 the pH is 0.82.
How do you find the pH of nitric acid?
Nitric acid is a strong acid meaning it completely dissociates in water. Therefore, you can say that the concentration of H+ ions in solution is the same as the concentration of the acid (molar concentration). So once you have that, you can use the pH formula to find the pH of the acid. pH = -log[H+]
What is the molarity of HNO3?
Molecular weight of HNO3 is 63.1 g/mole which in turn means: 1059.1/63.1 = 16.78 M. So our molarity is 16.78 for this concentration. -log[16.78]=-1.22 so a negative PH! (it’s that acid :D). Some people don’t consider negative pH to exist but that’s another story.
How do you calculate pH in chemistry?
Calculate pH by using the pH equation: pH = -log 10 [H 3 O + ]. Know what pH actually is. The pH is a measure of the concentration of hydrogen ions in a solution.
