Which of the following cell can produce maximum electrical work?
`["Given" : P_(H_(2))=1 atm, K_(a)(CH_(3)COOH)=K_(b)(NH_(4)OH)=10^(-5)]`

% hydrolysis of 0.1M CH_(3)COONH_(4), when K_(a)(CH_(3)COOH)=K_(b)(NH_(4)OH)=1.8xx10^(-5) is:

% hydrolysis of 0.1M CH_(3)COONH_(4), when K_(a)(CH_(3)COOH)=K_(b)(NH_(4)OH)=1.8xx10^(-5) is:

NH_(4)OH , NaOH, CH_(3)COOH , H_(2)S

pH of a solution of 0.1 M [CH_3COONH_4(aq)] is [given: K_a(CH_3COOH) = K_b(NH_4OH) = 1.8 x 10^-5)]

Calculate the pK values of the following organic acids and bases from their given K constants: (a) CH_(3)COOH,K_(a)=1.8xx10^(-5) (b) CH_(3)OH,K_(a)=3.1xx10^(-16) (c) CH_(3)NH_(2),K_(b)=4.5xx10^(-4)

A galvanic cell is compsed of two hydrogen electrodes, one of which is a standard one. In which of the following solutions should the other electrode be immersed to get maximum emf? K_(a)(CH_(3)COOH) = 2 xx 10^(-5) , K_(a)(H_(3)PO_(4)) = 10^(-3) .
