Answer:
We space have space

pH space space plus space pOH space equals space 14 space

pH space equals space 12

12 space space plus space plus space pOH space equals space 14

pOH equals space 2 space space

pOH space equals space minus log open square brackets OH to the power of minus close square brackets

open square brackets OH to the power of minus close square brackets space equals space antilog left parenthesis negative 2 right parenthesis


open square brackets OH to the power of minus close square brackets space equals space 0.01 space straight M

Ba left parenthesis OH right parenthesis subscript 2 space space rightwards arrow space Ba to the power of plus 2 end exponent space space plus space space 2 OH to the power of minus

At space equilibrium comma space
Ba to the power of plus 2 end exponent space equals space straight x

space OH to the power of minus space equals space 2 straight x

therefore 2 straight x space equals space 0.01

space straight x space equals space 5 space cross times 10 to the power of negative 3 end exponent space straight M

Ba to the power of plus 2 end exponent space equals space 5 space cross times 10 to the power of negative 3 end exponent space straight M

straight k subscript sp space end subscript space equals space open square brackets space Ba to the power of plus 2 end exponent close square brackets open square brackets OH to the power of minus close square brackets squared

space space space space space space space space space equals left square bracket space space 5 space cross times 10 to the power of negative 3 end exponent right square bracket space cross times left square bracket 0.01 right square bracket squared

space space space space space straight k subscript sp space end subscript equals 5 space cross times 10 to the power of negative 7 end exponent space space straight M cubed
