if the ph of a 0.133 m solution is 10.66, what is the ionization constant of the base?
express your answer using two significant figures.

Kb = 1.6*10^-6

Explanation:

The given reaction is:

The ionization constant of the base Kb is given as:

The pH = 10.66

therefore, pOH = 14-pH = 14-10.66 =3.34

[N2H5+] = [OH-] = 4.57*10^-4M

[N2H4] = 0.133 M

Based on eq(1)

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
