What is the pKa of perchloric acid?

What is the pKa of perchloric acid?

≈ -8
Perchloric acid (HClO4): pKa ≈ -8. Hydrochloric acid (HCl): pKa = -6.3.

Is perchlorate a strong acid?

It provides strong acidity with minimal interference because perchlorate is weakly nucleophilic (explaining the high acidity of HClO4). Other acids of noncoordinating anions, such as fluoroboric acid and hexafluorophosphoric acid are susceptible to hydrolysis, whereas perchloric acid is not.

What is hcio4?

Perchloric acid is a chlorine oxoacid. It is a conjugate acid of a perchlorate. ChEBI.

What is the pH of perchloric acid?

1.55
The pH of the perchloric acid solution is 1.55. The pH of an acid can be calculated by taking the negative log of the hydrogen ion concentration in…

How do you find the pH of perchloric acid?

1 Answer

  1. We use the pH equation, which states that,
  2. pH=−log[H+]
  3. And so, the pH will be,
  4. pH=−log[0.075]
  5. ≈1.12.

Is perchloric acid a binary acid?

Simple acids, known as binary acids, have only one anion and one hydrogen. Therefore, HClO4 is called perchloric acid. With one fewer oxygen than the “-ate” ion, the acid will have the suffix “-ous.” For example, chlorous acid is HClO2.

What is the PH of hydroiodic acid?

3.01
pH of Common Acids and Bases

Acid Name 1 mM
H2SO4 sulfuric acid 2.75
HI hydroiodic acid 3.01
HBr hydrobromic acid 3.01
HCl hydrochloric acid 3.01

Is hydroiodic acid conductive?

Using a simple and low temperature dipping treatment in hydriodic acid (HI) solution, we have fabricated a highly conductive and transparent poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) and graphene oxide (GO) hybrid film.

How do you prepare Acetous perchloric acid?

Preparation of 0.1 N Acetous Perchloric Solution

  1. To approximately 500 mL of glacial acetic acid (CH3COOH, Sp gr 1.05) in a 1-L volumetric flask,
  2. Add 8.5 mL of 70 % perchloric acid (HClO4, Sp gr 1.67) and mix the solution by swirling.
  3. Dilute to volume with glacial acetic acid and mix again.

What is the pH of hydrochloric acid?

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.

Is hydrocyanic acid a binary acid?

All acids beginning with the prefix „hydro“ are otherwise known as binary acids. HCl, which contains the anion chloride, is called hydrochloric acid. HCN, which contains the anion cyanide, is called hydrocyanic acid.
