What is the difference between the titration of a strong acid-strong base versus a weak acid weak base?
In a strong acid-strong base titration, the equivalence point is reached when the moles of acid and base are equal and the pH is 7. In a weak acid-strong base titration, the pH is greater than 7 at the equivalence point. In a strong acid-weak base titration, the pH is less than 7 at the equivalence point.
How conductometric titrations are different from acid base titrations?
A solution conducts electricity if there are mobile ions in solution. This solution is referred to as an electrolytic solution. In an acid-base conductometric titration the changes in the conductivity of the solution, its conductance, is measured as the base is gradually added to the acid (or as acid is added to base).
Which of the following indicators is are used in the conductometric titration of strong acid versus strong base?
We have to choose the indicator for titration of a strong acid and strong base. In this case any indicator that has pH range 3.5 to 10 is capable of identification of equivalence point or end point. So, among the given options, methyl orange and phenolphthalein can be used as indicators in acid base titration.
What is conductometric titration of strong acid and strong base?
Conductometric Titration of strong acid and strong base: In a strong acid-strong base titration, the acid and base will react to form a neutral solution. The conductance of electrolytes depends on the number of ions and their speeds.
Why is conductometric titration better than normal titration?
Advantages of Conductometric Titration As the end point is determined graphically, results are more accurate with minimum error. It is used for analysis of turbid suspensions, weak acids, weak bases, mix of weak and strong acids etc.
Why conductometric titrations are preferred more?
More accurate results are obtained by conductometric titrations because the end-point is determined graphically from a number of measurements and not from a single measurement as in volumetric titration. This titration can be used with colored or opaque solutions in which endpoint cannot be seen by the naked eye.
What is the basic principle of conductometric titration?
The principle of conductometric titration is based on the fact that during the titration, one of the ions is replaced by the other and invariably these two ions differ in the ionic conductivity with the result that conductivity of the solution varies during the course of titration.
Why is it better to titrate a base into acid?
The purpose of a strong acid-strong base titration is to determine the concentration of the acidic solution by titrating it with a basic solution of known concentration, or vice-versa, until neutralization occurs. Therefore, the reaction between a strong acid and strong base will result in water and a salt.
