What is Ka of HNO2?

What is Ka of HNO2?

Ka = 4.5 x 10. -4. for HNO2. HNO2 ⇄ H+ + NO2.

What is the Ka of hno3?

2.4 * 101

Ka	Acid
1.0 * 109	Hydrobromic acid	HBr
1.3 * 106	Hydrochloric acid	HCl
1.0 * 103	Sulfuric acid	H2SO4
2.4 * 101	Nitric acid	HNO3

What is the Ka value of h2co3?

It should be noted that carbonic acid is a weak acid, so its Ka value in water is only 4.3 x 10^-7.

What is the Ka value of HClO?

3.0 x 10-8
The Ka of hypochlorous acid (HClO) is 3.0 x 10-8 at 25 deg C.

How do you find Ka of HNO2?

1. A) For nitruos acid, HNO2, Ka = 4.5 10-4. What is the equilibrium constant for the following reaction? NO2.
2. – + H3O+
3. ⇔ HNO2. + H2O. 1) 2.2 10-11.
4. – + H3O+
5. This is just the inverse of the equation given in the problem, therefore K=1/Ka. K= 2.2 103.
6. -,
7. Kb reaction: NO2.
8. – + H2O ⇔ HNO2.

How do I calculate 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.

How do you find the Ka value?

What is Ka of HF?

Ka for HF is 3.5 × 10^-4 .

Why does carbonic acid have two PKAS?

All Answers (8) There are multiple hydrogen atoms on the molecule that can be deprotonated. A molecule with two pKa values indicates the presence of two different inonizable functional groups.

What is the Ka of NaOH?

4.6
It corresponds to a volume of NaOH of 26 mL and a pH of 8.57. The half equivalence point corresponds to a volume of 13 mL and a pH of 4.6. The value of Ka from the titration is 4.6.

What is the Ka of HC2H3O2?

The Ka for HC2H3O2 is 1.8 x 10-5.
