Step 1: Given data

Given:

Given is a solution of CH3NH3NO3

Concentration of solution = 0.20 space straight M

Temperature = 25oC

straight K subscript straight b space o f space C H subscript 3 N H subscript 2 equals space 4.4 cross times 10 to the power of negative 4 end exponent
straight K subscript straight a space o f space H N O subscript 3 equals space 2.4

The pH of a solution is determined using the negative logarithm of the hydrogen ion concentration (H+). The pH of a solution is a measure of its acidity or alkalinity.
