Mark the appropriate choice to fill up the blanks in the given paragraph. A solution which maintains constant pH when small amounts of acid or base are added is known as a `ul((i))`. A mixture of acetic acid and sodium acetate acts as `ul((ii))` with a pH around `ul((iii))` and a mixture of ammonium chloride and ammonium hydroxide acts as `ul((iv))` with a pH around `ul((v))`A. `{:((i),(ii),(iii),(iv),(v),),("buffer capacity","basic buffer",9.25,"acidic buffer",4.75,):}`B. `{:((i),(ii),(iii),(iv),(v),),("buffer solution","acidic buffer",9.25,"basic buffer",4.75,):}`C. `{:((i),(ii),(iii),(iv),(v),),("buffer solution","basic buffer",4.75,"acidic buffer",9.25,):}`D. `{:((i),(ii),(iii),(iv),(v),),("buffer solution","acidic buffer",4.75,"basic buffer",9.25,):}` |
