The volume of the base should be gradually increased, stopping once the equivalence point is achieved. At the volume halfway between the equivalence point and the acid, the acid's pKa is equal to the pH.
<h3>What is titration, for instance?</h3>
Titration, sometimes referred to as titrimetry, is a method for calculating the concentration of a specific analyte in a mixture that is used in chemical qualitative analysis. Titration, which is also sometimes referred to as volumetric analysis, is a crucial analytical chemistry method.
<h3>What governs titration in its basic form?</h3>
The following is the fundamental titration principle: The sample being studied is given a solution, referred to as a titrant or standard solution. A chemical is present in the titrant in a known concentration.

Answer:
Balanced reaction: 
S is oxidized and N is reduced.
is the oxidizing agent and ZnS is the reducing agent.
Explanation:
Reaction: 
Oxidation: 
Balance charge: 
...............(1)
Reduction: 
Balance H and O in acidic medium : 
Balance charge: 
...............(2)
[
Equation-(1)] + [ 
Equation-(2)]:
Oxidation number of S increases from (-2) to (0) for the conversion of ZnS to S. Therefore S is oxidized.
Oxidation number of N decreases from (+5) to (+2) for the conversion of to NO. Therefore N is reduced.
consumes electron from ZnS. Therefore is the oxidizing agent and ZnS is the reducing agent.
Answer:
Calcium
Explanation:
Clacium has atomic number 20. The atomic number. This means that it has 20 protons and 20 electrons. it has 21 neutrons.
