Answers

Yes, It is important to know the volume of Unknown acid or base to be titrated.

Titration is carried out in order to find out the concentration (i.e. molarity) of unknown acid or base. In this process a standard solution of acid or base is taken and is titrated with known volume of of titrant. At end point (neutralization) the amount of standard titrant utilized is calculated and following formula is employed to calculate the unknown concentration of unknown solution.

M₁V₁/n₁ = M₂V₂/n₂

Answer from: jordanlacie65

YES

Explanation:

Titration is an analytical method or technique which is used to determine the concentration of an unknown solution, called analyte; by using a solution of known volume and concentration, called titrant.

In this method, the volume of the titrant used to neutralize the given analyte is noted and then the concentration of the unknown solution or the analyte is calculated by using the following equation:

$C_{titrant}\cdot V_{titrant} = C_{analyte}\cdot V_{analyte}$

Here, $C_{titrant}$ is the known concentration of the titrant

$C_{analyte}$ is the unknown concentration of the analyte

$V_{titrant}$ is the volume of the titrant used during the titration

$V_{analyte}$ is the known volume of the analyte

Therefore, in order to determine the concentration of the unknown solution or the analyte, the exact volume taken should be known.

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.
