Chapter 16, Problem 1STP

Interpretation Introduction

Interpretation: The wrong pair of conjugate acid-base pair is to be determined.

Concept introduction The concept of conjugate acid-base pair is given by Arrhenius.

According to it,

Acid is a substance which donate hydrogen ion and Base is a substance which accept hydrogen ion.

When acid donates $H^{+}$ , the species form is conjugate base and when base accepts $H^{+}$ , the species form is conjugate acid.

Answer to Problem 1STP

Option B.

Explanation of Solution

When acid donates positive ion or proton, the acid turns into a base, and whenever a base accepts that proton or positive ion, an acid is formed. Both acids and bases are differentiated on the basis of presence or absence of a ion are called conjugate acid-base pair.

Conclusion

All the other optons are conjugate acid-base pair.
