How do you calculate the pH of nitric acid?
How do you calculate the pH of nitric acid?
Therefore, since is it also monoprotic (it provides one mole of hydrogen ions per mole of acid), the concentration of hydrogen ions in solution equals the concentration of the acid i.e. 0.125M. Now we simply use the equation that defines pH, thus: pH = -lg [H+] = -lg0. 125 = 0.903 (to 3s.
What is the pH of a 1M solution of HNO3?
The obvious answer is a pH of zero when substituting the 1M value into the definition of pH.
What is the pH of a 0.01 M solution of nitric acid?
So… [HNO3] = [H+] = 0.01 M pH = – log [H+] = – log [0.01] = 2.0 Page 5 Chem 30: Acid-Base Equilibria Welter Class Notes Example 2: Find the pH of a 0.01 M solution of ammonia. Solution: NH3 is a weak base with Kb= 1.8 × 10-5 (always look up with weak acids/bases).
What acid has a pH of 1?
The pH scale
| Increasing pH (Decreasing Acidity) | Substances |
|---|---|
| 0 (most acidic) | Hydrochloric acid (HCl) |
| 1 | Stomach acid |
| 2 | Lemon juice |
| 3 | Cola, beer, vinegar |
What is the pH of a 0.01 M solution of NaOH?
13
NaOH is a strong base, so this will produce 0.1mol/L of OH ions in solution. This will produce a pH of 13. Therefore, the pH of 0.1 M NaOH solution is 13. Note: The pH scale, which ranges from 0 to 14, tells you how acidic or alkaline a solution is.
What is the pH of HCl?
1.000
Since HCl is a strong acid, it completely ionizes, and the pH of HCl in solution can be found from the concentration (molarity) of the H+ ions, by definition equal to 0.100 M. (The conjugate base of the acid, which is the chloride ion Cl–, would also have a concentration of 0.100 M.) The pH is thus –log(0.100) = 1.000.
What is the pH of 0.5 M HNO3?
The pH of a 0.50 M HNO3 solution is 1.83.
Why does NH4Cl have low pH?
Acidic Nature and Uses The slightly acidic nature of ammonium chloride is due to the formation of hydrochloric acid (HCl), because HCl is a strong acid and its effect is dominant. Determine the acidic or basic nature by using a pH meter.
Does NH4Cl have a high pH?
The aqueous solution of ammonium chloride is slightly acidic having a pH value range from 4.5 to 6. Ammonium chloride is a strong electrolyte because it dissolved fully into ions or 100% ionized in an aqueous solution. 1 Why NH4Cl acts as acidic salt?
How to calculate the pH of a nitric acid solution?
What is the pH of a 0.1 M solution of Nitric Acid HNO 3(aq) H+(aq) + NO 3-(aq) 0.1 M acid makes a solution with [H+] = 0.1M pH =-log(0.1) = 1
How do you determine the pH of a 0.125 M solution of?
Therefore, since is it also monoprotic (it provides one mole of hydrogen ions per mole of acid), the concentration of hydrogen ions in solution equals the concentration of the acid i.e. 0.125M. Now we simply use the equation that defines pH, thus:
What is the pH of HF and Hno?
pH of Common Acids and Bases Acid Name 1 mM 10 mM 100 mM HF hydrofluoric acid 3.27 2.65 2.12 HNO 2 nitrous acid 3.28 2.67 2.13 HCyanate isocyanic acid, HOCN 3.35 2.76 2.23 HFormate formic acid, CH 2 O 2 (methanoic acid) 3.47 2.91 2.38
What is the health hazard of nitric acid?
