Chapter 10: Q.10.102 (page 360)

For each of the following:

1. HCN

2.NH4+

a. Write the formula for the conjugate base.

b. Which is the stronger acid?

Short Answer

Expert verified

Part (a) . conjugate bases are- CN-and NH3

Part (b) . HCN is the stronger acid

Step by step solution

01

   Information Part (a) 

In the Br酶nsted-Lowry meaning of acids and bases, a conjugate acid-base pair comprises two substances that vary exclusively by the presence of a proton (H鈦�). A conjugate acid is framed when a proton is added to a base, and a conjugate base is shaped when a proton is eliminated from an acid.

02

Explanation Part (a)

A conjugate base is shaped when a proton is eliminated from an acid.

The conjugate bases are-

HCN-CN-and NH4+-NH3

03

Explanation Part (b)

HCN is the stronger acid as the conjugate base is weaker.
