What are concordant reading? write for 4 marks chemistry
Answers
Answer:
Concordant readings are frequently encountered in titrations in chemistry, where titre values are said to be concordant if they are within 0.20 cm3 of each other.
Control variable: A control variable is one that will affect the outcome of the investigation.
Titres that are within 0.05 mL of each other are said to be concordant titres. If you have a titre that is not close to the other titres, record it, BUT ignore it! This titre will NOT be used in any calculations.
Obtaining results:-
The titre will depend upon the volume of liquid in the conical flask, and the concentrations of the acid and alkali used. Repeat the titration several times until the titre is concordant (you have at least two titres within 0.20 cm 3 of each other).
Purpose of obtaining at least three concordant results:-
A titration is repeated at least three times in order to provide a statistically valid answer
