Please answer this question...:

Q.  A buffer solution can be prepared from a mixture of.
a) NH4Cl and NaOH in 2:1 mole ratio
b) CH3COONa and HCl in 1:1 mole ratio.
c) CH3COONa & HCl in 2:1 mole ratio
d) CH3COONa and HCl in 1:2 mole ratio. 

 

Dear Student,

The correct answer is (a) and (c)NH4Cl is a salt of weak base and NaOH is a strong acid. So if double moles of NH4Cl is taken, then it can act as buffer. Similarly, CH3COONa and HCl in 2:1 ratio will act as buffer
