What is the Ka of HClO4?
| Ka | Acid | |
|---|---|---|
| Name | Formula | |
| Large | Perchloric acid | HClO4 |
| 3.2 * 109 | Hydroiodic acid | HI |
| 1.0 * 109 | Hydrobromic acid | HBr |
How do you convert pH to Ka?
As noted above, [H3O+] = 10–pH. Since x = [H3O+] and you know the pH of the solution, you can write x = 10–2.4. It is now possible to find a numerical value for Ka. Ka = (10–2.4)2 /(0.9 – 10–2.4) = 1.8 x 10–5.
What is the pH of hydrochloric acid solution?
1.5 to 3.5 Hydrochloric acid is an essential component of gastric acid, which has a normal pH of 1.5 to 3.5. A weak acid or base does not ionize completely in aqueous solution. Ionization of a weak acid (HA) is characterized by its dissociation constant (Ka).Can you have a negative pH?
It’s definitely possible to calculate a negative pH value. … In practice, any acid that yields a concentration of hydrogen ions with a molarity greater than 1 will be calculated to have a negative pH.
