Moles of titrant are lost in the calculation in redox titration.
"The process of calculating the quantity of a material A by adding measured increments of substance B, the titrant, with which it reacts until exact chemical equivalency is obtained (the equivalence point)" is the definition of titration.
The equivalence point, or the point at which chemically equivalent amounts of the reactants have been combined, is to be detected by the titration. The stoichiometry of the reaction determines how many reactants have been combined at the equivalence point.
Titration, commonly referred to as titrimetry, is a method of chemical qualitative analysis used to determine the concentration of a certain analyte in a mixture. In the realm of analytical chemistry, titration is a crucial technique.

Answer:
radiation
Explanation:
radiation is the transfer of heat energy through space by electromagnetic radiation
Answer:
C₂H₆
Explanation:
To obtain molecular formula of the gas, you need to find first its molecular mass.
To find molecular mass you need to obtain moles of gasbecause molecular mass is the ratio between mass of the gas and the volume it occupies.
As at STP, 1 mole of a gas occupies 22.4dm³, 1dm³ of gas are:
1dm³ × (1mol / 22.4dm³) = 004464moles.
Its molecular mass is:
1.35g / 004464moles =
30.24g/mol
Now, if the gas is 80%C and 20%H, its <em>empirical formula (Simplest ratio of atoms in a molecule) </em>is:
80% Carbon × (1mol / 12.01g) = 6.66moles C
20% Hydrogen × (1mol / 1.01g) = 19.8moles H
Ratio of H:C is:
19.8 mol H / 6.66mol C = 3
Thus, you can know you will have 3 moles of Hydrogen per mole of Carbon, CH₃ (It weighs 15.04g/mol)
As the gas weighs 30.24 ≈ 2 CH₃
The molecular formula is:
<h3>C₂H₆</h3>
