Calcualate pH,[H^(+)],[OH^(-)],[CH(3)COO...

Calcualate `pH,[H^(+)],[OH^(-)],[CH_(3)COOH],[SH^(-)],[H_(2)S],[S^(2-)]` in a solution obtained by mixing equal volume of `0.2M H_(2)S &0.02M` acetic acid .Given that
`K_(a)(CH_(3)COOH)=2xx10^(-5),K_(a_(1))(H_(2)S)=10^(-7),K_(a_(2))(H_(2)S)=10^(-14)` Take `log21=-1.32,(1)/(sqrt(21))=0.218`

Text Solution

AI Generated Solution

To solve the problem, we will follow these steps: ### Step 1: Calculate the concentrations after mixing When equal volumes of two solutions are mixed, the concentrations of the components are halved. - Initial concentration of \( H_2S = 0.2 \, M \) - Initial concentration of \( CH_3COOH = 0.02 \, M \) ...
