Transcribed Image Text:The value of K, for a
Expert Solution
Step 1
Acid donates hydrogen ions while base receives hydrogen ions. Ka is the acid dissociation constant and Kb is the base dissociation constant. Larger the value of Kb stronger is the base. Similarly, larger Ka value gives the stronger acid. By multiplying Ka× Kb
Gives the dissociation constant of water Kw whose value is 1.0×10-14
Step 2
So, desired equation is:
Given values:
Ka for acetic acid=1.80×10-5
Kw for water= 1.0×10-14
