1.	At 25^(@)C, the dissociation constant of a base, BOH is 1.0xx10^(-12). The concentration of hydroxy 1 ions in 0.01 M aqueous solution of the base would be :
Answer» `1.0xx10^(-6) "mol " L^(-1)` `1.0xx10^(-7) "mol " L^(-1)` `2.0xx10^(-6) "mol " L^(-1)` `1.0xx10^(-5)"mol " L^(-1)` Solution :`BOHhArr B^(+) + OH^(-)` `K=([B^(+)][OH^(-)])/([BOH]) = ([OH^(-)]^(2))/([BOH])` or `[OH^(-)]=SQRT(K[BOH])=sqrt(10^(-12)(0.01))` `=10^(-7)"mol" L^(-1)`
