Choose an option
Show full solutionCorrect option: C
Correct answer
CCH3COOK
Step-by-step explanation
Note :
When a salt is made with strong base and weak acid then that salt will be basic nature in aqueous solution.
(a) Pb(CH3COO)2 is a salt of weak base Pb(OH)2 and weak acid CH3COOH.
(b) Al(CN)3 is a salt of weak base Al(OH)3 and weak acid HCN.
(c) CH3COOK is a salt of weak acid CH3COOH and strong base KOH.
(d) FeCl3 is a salt of weak base Fe(OH)3 and strong acid HCl.
