What is the pKa of HCl?

Hydrochloric acid (HCl): pKa = -6.3.

What is ammonia pKa?

The pKa of ammonia itself is 38, which measures the equilibrium constant for dissociation of NH3 to give its conjugate base, NH2(-) and H+.

What is the Ka value of HCl?

What is carbamate in chemistry?

Carbamate is an amino-acid anion. It is a conjugate base of a carbamic acid. Included under this heading are N-substituted and O-substituted carbamic acids. In general carbamate esters are referred to as urethanes, and polymers that include repeating units of carbamate are referred to as POLYURETHANES.

What is KA and pKa in chemistry?

Ka is the acid dissociation constant. pKa is simply the -log of this constant. Similarly, Kb is the base dissociation constant, while pKb is the -log of the constant.

What is the pKa of NH3+?

For example the pKa of the – NH3+ group of alanine is 9.87 but the pKa of CH3NH3+ is 10.63. Explain why the pKa of the – NH3+ group of an a-amino acid is lower than the pKa of the ammonium ion derived from a 1° amine (RNH3+).

What is the pKa value of phenazine?

pKa Values INDEX Inorganic 2 Phenazine 24 Phosphates 3 Pyridine 25 Carboxylic acids 4, 8 Pyrazine 26 HCO3 10.33* HSe– 11.00* 77 H2CrO4 -0.98 30 H 2S 7.00* 77
