Which of the following will produce a buffer solution when mixed in eq

1.	Which of the following will produce a buffer solution when mixed in equal volumes ?
Answer» 0.1 mol `dm^(-3) NH_4OH` and 0.1 mol `dm^(-3)` HCl 0.05 mol `dm^(-3) NH_4OH` and 0.1 mol `dm^(-3)` HCl 0.1 mol `dm^(-3)NH_4OH` and 0.05 mol `dm^(-3)` HCl 0.1 mol `dm^(-3) CH_4COONa` and 0.1 mol `dm^(-3)` NaOH Solution :If the concentration of `NH_4OH` is higher than the strong ACID (HCl), a MIXTURE of weak BASE and its conjugate acid is obtained, which acts as basic buffer. `{:(,NH_4OH + , HCl to , NH_4Cl + ,H_2O),("INITIALLY", 0.1M,0.05 M, 0,),("After reaction",0.05 M, 0, 0.05 M,):}`
