Untuk menentukan pH larutan basa maka perlu ditentukan konsentrasi dari ion undefined. Larutan begin mathsize 14px style Fe open parentheses O H close parentheses subscript 3 end style maka menentukan konsentrasi dari ion undefined.
 

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell open square brackets O H to the power of minus sign close square brackets end cell equals cell square root of K subscript b cross times open square brackets Basa close square brackets end root end cell row blank equals cell square root of 3 cross times 10 to the power of negative sign 5 end exponent cross times 0 comma 2 end root end cell row blank equals cell square root of 6 cross times 10 to the power of negative sign 6 end exponent end root end cell row blank equals cell square root of 6 cross times 10 to the power of negative sign 3 end exponent end cell row pOH equals cell negative sign log space open square brackets O H to the power of minus sign close square brackets end cell row blank equals cell negative sign log space square root of 6 cross times 10 to the power of negative sign 3 end exponent end cell row blank equals cell 3 minus sign log space square root of 6 end cell row pH equals cell 14 minus sign left parenthesis 3 minus sign log square root of 6 right parenthesis end cell row blank equals cell 11 plus log space square root of 6 end cell row blank blank blank end table end style 


Jadi, pH dari larutan undefined 0,2 M adalah begin mathsize 14px style 11 plus log space square root of 6 end style.undefined
