Which statements regarding the henderson-hasselbalch equation are true? if the ph of the solution is known as is the pka for the acid, the ratio of conjugate base to acid can be determined. at ph = pk a for an acid, [conjugate base] = [acid] in solution. at ph > > pk a for an acid, the acid will be mostly ionized. at ph < < pk a for an acid, the acid will be mostly ionized. view available hint(s) which statements regarding the henderson-hasselbalch equation are true? if the ph of the solution is known as is the pka for the acid, the ratio of conjugate base to acid can be determined. at ph = pk a for an acid, [conjugate base] = [acid] in solution. at ph > > pk a for an acid, the acid will be mostly ionized. at ph < < pk a for an acid, the acid will be mostly ionized. all of the listed statements are true. 1, 2, and 3 are true. 2, 3, and 4 are true. 1, 2, and 4 are true.

1, 2, and 3 are true.

Explanation:

The Henderson-Hasselbalch equation is:

pH = pka + log₁₀

pH = pka + log₁₀

If you know pH and pka:

10^(pH-pka) =

The ratio will be: 10^(pH-pka)

pH = pka + log₁₀

0 = log₁₀

10^0 =

1 =

As ratio is 1,  [conjugate base] = [acid] in solution.

pH = pka + log₁₀

If pH >> pKa,  10^(pH-pka) will be >> 1, that means that you have more [A⁻] than [HA]

pH = pka + log₁₀

If pH << pKa,  10^(pH-pka) will be << 1, that means that you have more [HA] than [A⁻]

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

the maximum mass of nh3 is nh3 in grams
