Question

1- difference between Equivallence point and end point.
2- what is Amphoteric solvent and give example​

Answer 1

Answer:

1.

The main difference between equivalence and endpoint is that the equivalence point is a point where the chemical reaction comes to an end while the endpoint is the point where the colour change occurs in a system

2.This is what "amphoteric" means in Brønsted-Lowry acid-base theory. Examples include amino acids and proteins, which have amine and carboxylic acid groups, and self-ionizable compounds such as water. Metal oxides which react with both acids as well as bases to produce salts and water are known as amphoteric oxides.

Answer 2

Explanation:

What is the difference between Equivalence Point and End Point?

1 The equivalence point in a titration is the point at which the added titrant is chemically equivalent completely to the analyte in the sample. End point is the point where the indicator changes its color.

2 Equivalence point comes before the end point.

3 To get the same equivalent point as the end point, pH of the indicator should match the pH at the equivalence.

4 In equivalence point the moles of acid are chemically equivalent to that of the moles of base.

5 End point is the point of completion of the reaction between two solutions.
