Today, I frustratingly realized that pK b is not an equilibrium constant for the reaction of a base into it's conjugate acid.
22.
The reception of a proton by a base produces its " conjugate acid ", which is the base with a hydrogen ion added.
23.
Is the pka given for this substance the value of nitromethane as an acid, or its conjugate acid ( nitromethane is acting like a base )?
24.
Strawberry pigment extract can be used as a natural acid / base indicator due to the different color of the conjugate acid and conjugate base of the pigment.
25.
I just want to find out how much having the chloro groups on there influences the acidity of the amino proton as well as the pka of its conjugate acid.
26.
The buffer capacity merely means that the buffer only exists " so long as both parts of the conjugate acid / base pair exist in the solution ".
27.
H 2 O is a base because it accepts a proton from CH 3 COOH and becomes its conjugate acid, the hydronium ion, ( H 3 O + ).
28.
Where the pK a is that of the conjugate acid of the nucleophile and the constant 1.74 is the correction for the pK a of H 3 O +.
29.
The addition of H + to the H 2 O ( acting as a base ) forms the hydronium ion, H 3 O +, the conjugate acid of the base.
30.
I guess I'm surprised at the reactivity because RNH-is a considerably worse anion ( conjugate acid pKa 35 ) than RO-in the hydride donation to carbonyls.
