What is the Ka of C2H5NH3Cl?

What is the Ka of C2H5NH3Cl?

Student prepares ethylamine buffer by using 0.700 M C2H5NH2;0.620 M C2H5NH3Cl (kb= 5.6 x 10^-4 and ka= 1.785x 10^-11) HINT this is a buffer.

What is the pH of C2H5NH3Br?

What is the pH of 0.18M ethylammonium bromide, C2H5NH3Br. Enter your answer with two decimal places. The Kb of ethylamine, C2H5NH2, is 4.3 x 10-4. Selected Answer: 11.94 Correct Answer: 5.69 + 0.02.

Is Ethylammonium bromide an acid or base?

Ethylammonium bromide is a salt of a primary amine and the acid, HBr. A primary amine has the formula R-NH2. It is primary in the sense that there is only one alkyl group attached to the nitrogen atom. Primary amines are weak bases very similar to ammonia and so form salts with acids.

How do you calculate the pH of a buffer solution?

How to calculate the pH of a buffer solution?

  1. pH = -log₁₀(H);
  2. Ka – acid dissociation constant ;
  3. [HA] – concentration of the acid;
  4. [A⁻] – concentration of conjugate base; and.
  5. pKa = -log₁₀(Ka).

What is the Ka of ethylamine?

Dissociation constants of some acids and bases at 25°C (for pKa values click here)
arrange the compounds in decreasing K values

What is the pH of KF?

Anions of strong acids are such weak bases that they have no significant effect on the pH of a solution and are considered basic in water, why does KF have a pH greater than 7 and not a pH equal to 7?

What is the pH nh4cl?

7
While the question is too generic because it does not mention the values, we can say in general that the pH of Ammonium Chloride (NH4Cl) is less than 7. How we can say this? Well, if we look at the compound it is a salt of strong acid HCl and a weak base (ammonia).
