What is conductometric titration of weak acid and strong base?
Conductometric Titration of a weak acid and strong base: A titration is a controlled chemical reaction between two different solutions. For conductometric titration experiments, a known volume of the solution to be titrated is placed in a beaker and a conductivity cell dipped into it.
Is it possible to determine the conductometric titration of weak acid and weak base?
We can determine the volume of weak base needed to neutralize all the weak acid at the equivalence point for the neutralization reaction by reading it straight off the graph.
How do you calculate conductometric titration?
The strength of the acid can now be calculated via the formula S2 = (V1S1)/10; where S2 is the strength of the acid, V1 is the volume of base added (as per the equivalence point on the conductometric titration graph), and S1 is the strength of the base (already known).
How do you conduct a strong acid conductometric titration and a 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.
What is measured by Conductometry?
Conductometric measurements (conductance or conductivity) are related to the ability of a solution to carry an electric current while a constant alternating-current potential is maintained in a conductivity cell.
What is the indicator for weak acid-weak base titration?
Choice of Indicators
| Types of titration | Indicators |
|---|---|
| Strong acid-weak base | Methyl orange will change sharply at the equivalence point. |
| Weak acid-weak base | Neither phenolphthalein, nor methyl orange is suitable. No indicator is suitable because it requires a vertical portion of the curve over two pH units. |
How do you calculate corrected conductance?
Answer. The correction can be accomplished by multiplying the observed conductance either by total volume (V+V´) or by the factor (V+ V´)/V, where V is the initial volume of solution and V´ is the total volume of the reagent added.
What is the indicator used in the estimation of mixture of acids by Conductometry?
Acid-base titrations and redox titrations are often performed in which common indicators are used to locate the end point e.g., methyl orange, phenolphthalein for acid base titrations and starch solutions for iodometric type redox process.
What is conductometric titration write the basic principle of conductometric titration What are the advantages and disadvantages of conductometric titration?
The conductometric titration principle works on the fact that during titration one of the ions is replaced by another and this leads to a difference in the conductivity of both ions. This results in a variation of conductivity of the given solution throughout the titration through the principle of conductometry.
