Question

the equivalence point on a graph of pH versus the amount of titrant added to a solution? *​

Answer 1

Answer:

Titrant and analyte is a pair of acid and base. ... Equivalence point: point in titration at which the amount of titrant added is just enough to completely neutralize the analyte solution. At the equivalence point in an acid-base titration, moles of base = moles of acid and the solution only contains salt and water.

Answer 2

The equivalence point on a graph of pH versus the amount of titrant added to a solution

• The point at which an acid-base reaction is equivalent (the point at which the amounts of acid and of base are just sufficient to cause complete neutralization). The strength of the acid and base used in the titration affects the pH of the solution at the equivalence point.
• The titration's equivalence point occurs when precisely the right amount of titrant has been added to cause all of the drug being tested to respond, leaving no titrant behind.
• The equivalency point on the curve is the place where the graph is steepest. The colour shift that occurs during titration indicates that there is a quick and sudden change in pH at this location. An ICE table is necessary to determine volume and acidity at the equivalency point.
• The pH of a solution during a titration is represented graphically by a titration curve. When the moles of acid and base are identical and the pH is 7, the equivalence point in a strong acid-strong base titration is reached. At the equivalence point in a weak acid-strong base titration, the pH is higher than 7.
