1.	The acid ionization hydrolysis constant of Zn^(2+)is 1.0xx 10^(-9)which of the following statement are incorrect ?
Answer» The `[H_3O^(+) ]`ion concentration in 0.001 M `Zn Cl_2` solution is `1.0 xx 10^(4) ` The pH of 0.001 `M ZnCl_2 ` solution is 6 The basic dissociation constant of `Zn(OH)^(+)is 1.0 xx 10^(-5) ` The basic dissociation constant of `Zn(OH)^(+)is 1.0 xx 10^(5)` Solution :`K_(h_1)= ( K_W)/( K_(b_2) ) rArr K_(h_2 )= ( 1xx 10 ^(_14) )/(1 xx 10 ^(_19)) = 10 ^(-5) ` ` pH = 7 - ( P^(K_(b_2)))/( 2) - (1)/(2) log C= 7-(5)/(2) - (1)/(2) log 10 ^(-3)= 6` ` THEREFORE [H^(+) ] = 10 ^(-6) `
